3.5mm TRS jacks might cost 10 cents to include and then hundreds of dollars to service when they break. The issue is not the BOM cost.

Can you explain what do you mean by that? It is quite rare to see broken trrs jack on a laptop, at least I have never experienced one, nor on walkman or anything getting heavy plug/unplug use.
I thought it is an issue in reducing the cost to manufacture the case or something.
The jack actually broke on my old xps. Changing it with an aliexpress replacement took about 15 minutes and something like 3€
So yeah, they break, but they are (or used to be?) quite cheap to fix (and this was one of the super thin 13" xps)

I had a slim XPS13 and IIRC the headphone jack was on it's own little board. That makes it quick/easy/cheap to repair if you know what you're doing / have the service manual / are comfortable taking it apart.
Not all things are designed that way; sometimes the jack is right on the main board and most people that buy dell laptops are not going to DIY through ali express; they're going to use up phone support time, require a shipping label, technician time ... etc.
All physical receptacles break and increase failures by measurable amounts at mass-production scale.
You take care of your hardware, even during "heavy use," many people absolutely do not - and are downright abusive.
Many of these parts exhibit partial or intermittent failure modes where it's more expensive and difficult to determine warranty eligibility than to just fix the problem. Peanut butter in the jack, loose solder joints, whatever.
I’ve never had one break due to heavy use, but broke one on my work desktop due to forgetting I was wearing headphones and yanking on it when I got up.
Does anyone even do repairs anymore? Swap a motherboard and that's it.
So... swapping $100 component for a $0.3 break?
Doesn't this make including the jack even less justifiable?
Or don't swap it and live without the jack. But I have never seen a broken 3.5mm port but I've seen many, many broken or flaky USB-C ports.
Motherboard companies do hot air work, absolutely.
We've got laptops with modular USB-C ports that solve this effectively perfectly. An audio one would be even simpler. The only reason you don't see it everywhere is because they're being outrageously hostile to repairs, and choosing to charge you hundreds of dollars for repairs on a part that they know is easily broken.
Why is anything modular a good solution over a USB-C DAC-containing dongle cable?
Modular ports are a physical disconnect between "thing that routinely experiences stresses and has a relatively short expected lifespan under heavy use" and "extremely expensive and long-lived motherboard", usually a separate circuit board connected by a ribbon cable. They serve a completely different purpose from a dongle that converts a common port to a less common one.
Framework laptops have another decent strategy, where you've got on-motherboard ports that have relatively few usage cycles, and are protected from most forces because the easily-replaceable custom-dongle-squares are held in place quite securely. They take the damage, protecting the motherboard. And as long as the motherboard ports are still good, you can even forego the modular thing and just plug in directly if needed.
That’s the cost of doing it too cheaply: I’ve never had an Apple device fail but multiple cheap PCs were obviously designed by some MBA who overrode the mechanical engineers to save $0.10.
Since when is damage covered by warranty?
When you are unable to prove the issue wasn't a workmanship defect, also companies often eat these costs out of goodwill.
Furthermore, the warranty determination isn't free, either: in addition to the repair itself, some (likely multiple) employee's time was spent determining whether or not an issue existed at all, whether or not the issue was covered, whether it could be fixed, and facilitating the whole transaction.
Repairs also don't result in 100% yield. Depending on your company policy you might be eating the whole unit because of a mishap or just plain stubborn components/physical realities.
Repair fees don't cover all of the organizational moving parts required to actually carry out repairs.
