The reality is that the N900 Nokia was able to get mainstreamed in part because it had a fully ready to use OS developed from the 770 800 and 810s.
With the PP and PPp we still have massive usable life issues vs some half hacked Lineage or Graphine device, even SailfishOS is stuck using libhybris Android drivers.
To get good FOSS drivers form day one we are stuck(in the ARM-iverse) with a very small dev community and limited choices for supported bootloaders.
Maybe we can start getting flagship grade openRISC CPUs that don't thermal most of the battery into entropy and we can get back to successes like the Sharp Zaurus and Nokia Linux N-series but for now the little shops like Pine and historically OpenMoko have to use the chipsets available which so far is not making all but the most zealous satisfied while Nokia, Sharp and a few others created a great user experience but were full of blob drives making the Nokia and Sharp devices mostly un-unbridgeable until reverse engineered drivers became available sometime ten or more years later.
One thing to be sure of any android/IOS phone including hacks like graphine is that it is always an easy unlock with a Cellbrite dongle, the pinephone, libre, and any other fully free bootloader device with a fully encrypted disc is verified un-hackable.
