I think that the call to pgstat_report_activity in WalSndLoop() should
be kept as well. There is a small gap between the moment the process
is started and the first replication command is run.

Perhaps not, I found the idea funky but you actually don't want to
show a string in exec_replication_command for a T_SQLCmd node. That's
not complicated to check either. So let's discard such a thing for
now.
