I suppose, but if it requires sending a keyspace param w/ each call,
then it's not sensible.  You waste far more overhead for that in the
common case -- serializing, deserializing, checking that it's been
authed -- than you gain from not having another connection in the
uncommon one.

I would be okay with being able to send a 2nd auth call to an existing
connection to switch the "current" keyspace, similar to how rdbmses
only have one active schema at a time.
