I cannot imagine that we'd ever make SELECT inside a plpgsql function
act like that. Functions have no business directly transmitting
information to the client; if they tried, they'd most likely just break
the FE/BE protocol.
There might be use for such a thing in a hypothetical "real stored
procedure language" where the code is executing in a context entirely
different from what Postgres functions run in ... but that language
would be something different from plpgsql.
I grant the argument that people coming from Sybase-ish DBs might be
confused by this; but the current arrangement is also confusing lots
of people, so I don't think that argument has all that much weight.
