I think this is an overly narrow view of "efficiency". With client
control, the client can insert savepoints whereever it needs them,
which might not be for every statement. Savepoints that you don't
actually need are going to be a fairly expensive overhead, AFAICS.
Also, in the V3 protocol, sending along extra BEGIN and COMMIT commands
doesn't have to cost you any extra network round trips.
