Logical slots behave differently than physical slots and need different
options. So to me there's a fair point in having support for
manipulating logical slot in a tool around logical slots.
Additionally that support was there in 9.4 and I know at least of three
scripts that call pg_recvlogical to create logical slots. Admittedly one
of them is of my own creation.

It's not that uncommon to have replicas only access the primary for
replication type connections. So it seems completely sensible to use the
replication protocol to manage slots. And that you can't really do with
psql.
