I tend to agree with it being confusing. Simpler might be to just
depend on pgbackrest and automatically set up archiving and backups.

No. Lots of users use archiving and until we've got a real answer to
being able to perform bulk archiving at scale, that's not likely to
change. pg_receivewal is absolutely not reasonable as a solution to
WAL archiving and management.
We've considered adding WAL streaming support to pgbackrest but it's not
much of a priority because it's rather ugly and not particularly better
than archive_command for most use-cases. Of course, we'd certainly
encourage folks to work with us to develop it and send us patches for
it.
Thanks,
Stephen
