While I've occasionally had an engine part fail most of the major repairs I've needed to do to cars over the years has been suspension related, it's consistently abused and closest to the road / debris.
That said... many of the different EVs sit on the same base, so maybe it won't actually be as hard to get parts as it seems.
It's not just repairs, maintenance too
Oil changes, timing belts, spark plugs etc. It really helps if you have no metal touching metal
Sure, but EVs also often have cooling loops that need service, your same cabin air filters, and more frequent tire and brake service due to heavier weights.

If you're talking about ac, sure. The rest, no? I've been driving an electric car for over a decade and have been replacing tires, and nothing else.
Sure it is anecdata with n of 1 but in over a decade I've probably spent ~4k on maintenance while driving 120k miles electrically? The bulk of that on tires and fixing that ac I mentioned.
Maybe frequent tire service, but they actually need less brake service because you are relying on regen instead of braking most of the time. I still can't believe the anti-EV crowd still doesn't get that one simple thing, it makes them look very non-credible.
Chinese EVs are more eclectic than western EVs. But ya, suspension parts....are those things that automakers innovate on? Though I guess BYD is an exception, since they own their own parts maker.
Innovation is rare among the broad consumer car market but modify to fit new bodies and motor layouts, yes, for sure. For most mainstream cars however you'll often find that a few models per generation for any given manufacturer either share parts or are interchangeable.
