Anyone know whether this is a sign of a push for being daily driver quality? Or a sign that volunteers previously doing promising work have drifted away, and they're acknowledging that?
Unfortunately there was/is no device supported by postmarketOS that fits that description. You'll need at least good telephony support including 4G features like VoLTE, proper camera support (not potato polaroid from the 80s quality), Wifi, Bluetooth, geolocation, working GPU acceleration, media hardware decoders, decent battery life. And I'm probably forgetting a few things.
Let's hope that initiatives like https://liberux.net/ will help make a fully working, long lasting device available!
I think the only realistic alternative would be to build upon AOSP properly, with Google being just a contributor instead of the owner. But it cannot come from a community fork by someone in their garage, it has to come from Android manufacturers. I was hoping that Huawei would start something like that, instead they went with their own HarmonyOS.
A blanket statement of a phone being "of daily driver quality or not" is impossible to make because everyone has different expectations of a "daily driver". I have been daily-driving the PinePhone since 2021 (it is my first and only smartphone) but that doesn't mean everyone else will be happy with it.
