PostmarketOS has a list of officially supported devices. Sadly that list is empty. We can wait but it's not going to happen by itself. Maybe everyone interested could fund a dev working on getting one device to be officially supported? I don't know if that would be welcome by the project. My point is, with the current pace, is the goal moving closer or further away?

Probably not time yet. The interim is an alternate OS such as lineage or graphene. Don't use google play and you're fine.

Basically that's a short term solution to wait out this stupid policy to get fixed, or if they double down it gives Linux phones a bit more time to come to market (I have not used one, but its essentially unanimous they are not ready to be a replacement today).
