Aren't you confused by the same thing as I was upthread [1]?

remote_apply affects all sessions. So even if you use a replication
role with synchronous_commit = on and have pg_receivewal use that with
remote_apply set in postgresql.conf, then remote_apply is effective
for all the other sessions so these will still be stuck at commit
waiting for pg_receivewal to apply WAL if it is a synchronous
standby.
