No, it does not. All that is required is that the users in question be
routed by one means or another to the virtual(8) transport, and that
smtpd(8) be given appropriate recipient validation tables for each
address class.
You can split the domain by rewriting, via mailbox_transport_maps or
via per-user transport_maps. Each choice has different pros/cons.

Rewrite (virtual(5)) selectively to a virual domain, or route
(transport(5)) selectively to the virtual(8) transport, or hand-off
mailbox delivery (mailbox_transport_maps) selectively to a virtual
transport.
