Thank you a lot for your insight about the state of react-prosemirror - that sounds promising already! We are currently still in the ‘which editor to pick finally’ last phase, with lexical being the last competition. But for sure we would update or PM-PoC using react-prosemirror next.
One thing I have open is @marijn statements in Official Roadmap or future plans - #2 by marijn
attached to it. react-prosemirror might be worth looking at if you want to put React components inside of the editor, but comes with its own complications, due to the way React introduced hard-to-control synchronicity.
@marijn could you comment on what you mean by " React introduced hard-to-control synchronicity"? Are you talking about something recent that has been added or a general concept?
