+1. The only point I'm not clear on is the complexity, and I trust you
to cut off at the right point here… meanwhile, I'm still asking for this

That would be awesome.
Then pg_streamrecv could somehow accept options that make it suitable
for use as an archive command, connecting to your (still?) third-party
daemon? At this point it'd be pg_walsender :)
