@k.eleni There's really no pipeline. It highly depends on individuals who have the device and willing to do the work and risk their device for bricking. So far, there's not much good history for both Samsung and Pixels. Pixel 3a has a good port but I think it won't even get VoLTE because of some issues with it stack being too old. I don't know if there's any Samsung port that is good. The safer bets are the Fairphones and Volla phones. Also not that I'm pushing away, if your concern is privacy then maybe Android ROMs like GraphineOS would suffice?
