Effect: we would stop receiving complaints that an old pg_dump can talk
to a server that most likely is incompatible with it.  People would
learn on the spot that they must install the newer pg_dump.

Implication: you cannot dump a newer database and expect it to load on
an older server (it would work for certain versions, but not all).  So
if people have a bleeding-edge test server, they cannot migrate stuff
from it to their older production server.
