Good points by Asonix. As for LineageOS, on the list of active LOS installs, the Pro1 sits in 953rd place with 446 installs. ROM-porting isn't trivial, and I can't see anyone capable to do this spending time on a ROM for the successor to a model that has 446 installs -- the most active model has 441,000 installs). If the shipment ever reaches me, I'll follow Asonix and put the device away until LOS 19 rolls around ... I hope this doesn't turn into long-term storage.
