I'd think client-side, we have an existing implementation with the
parallel pg_restore option. Don't know (yet) how easy it is to reuse
that code…

You're talking about the pg_streamrecv binary? Then yes, my idea about
it is that it should become the default archive client we ship with
PostgreSQL. And grow into offering a way to be the default restore
command too. I'd see the current way that the standby can switch
between restoring from archive and from a live stream as a first step
into that direction.
