I don't think anyone is especially happy about the LineageOS shortcomings you point out, but that's why people are working on supporting the mainstream Linux stack on existing hardware.

The LineageOS folks have a very difficult job to do, they must keep up with developments in AOSP while supporting dozens of existing hardware models, each with its own "exciting" quirks. Is it really any wonder that some hardware gets dropped from official support? Usually that just means bugs have turned up which would make LineageOS not fully usable on the hardware, and they don't have the volunteer manpower to address them.

Complaining about SafetyNet and microG is even less understandable, as these will always amount to unsupported hacks and we don't really need them for a usable device. Just get your apps from F-Droid, and you won't have to care about either.
