Eh, that's a multi-faceted question. I personally am tired of Pine. They've made some questionable calls over the past couple years and their "make open hardware with almost nothing working software-wise and see what the community does" business plan has started feeling exploitative to me.

PPpro was mismanaged especially badly. Nothing against the amazing community- it's just there were some hardware/firmware decisions by pine that made it especially hard to develop for. Meanwhile, the non-pro version is handicapped by a very slow processor.

There's still some development happening, and the window managers like KDE are still improving stuff on the front end. But you're right, it has slowed down. That all said, this is still the only non-Google/Apple device you can get in the USA that actually kinda works. I used both the non-pro and pro versions for a few months a couple years ago as my daily driver. I could make calls, send texts, connect to matrix, etc. I wouldn't claim that "it just worked" but it did work.
