The absolute newest Mac in my home is a 2017 and is limited to 13.7.8, also. It's still a beast, and I've never really thought of it as "old." The macOS (and iOS) ecosystem, though, is brutal on us "slightly older" hardware owners. We get dropped so quickly, by both Apple and by 3rd party developers.
Windows developers would think nothing of keeping their applications running on Windows 7 (16 years old) or Windows 10 (11 years old), but my 9 year old Mac is somehow ancient.
