Indeed.   The original intended use case for PVDs was for situations where a host is multiply connected, or where a network is multiply connected, and the configuration that works on one egress will not work on the other.   Another use case is the case where one apparent egress may not work at all until captive portal authentication has happened, and the information received from that egress, if used for the other egress, would cause the working egress to suddenly stop working.

The Terastream use case is a cute hack, but not a primary use case.   Mikael is reporting it because it’s a problem for him, not because it is the primary use case for PVDs.
