Would something like max_logical_wal_senders also be needed for your purpose?
Otherwise, logical replication connections could exhaust max_wal_senders and
prevent physical replication connections from being established.

That said, adding two separate GUC parameters (i.e.,
max_logical_replication_slots
and max_logical_wal_senders) for this purpose doesn't seem like a
great solution,
though...
