There are phosh based phones and over time more people will hopefully switch to them, use them, and work on making them better. Phosh-based phones are currently are not as usable as something like GOS, but with Google challenging itself to become more and more enshitified in the interest in marginal tiny profit gains (even if it destroys their brand over the long term) nerds needs to band together prepare for an alternative. Part of this is going to be advocating for Apps that work in Linux mobile Phosh environments and just refusing to use containerized apks and part of it is going to be people doing what they can to support native linux phone apps that work well in Phosh.
