Well, you could sorta do that, but the case that would stop working is
pg_restore output to a plain text SQL script (and related issues such as
the ability to use the feature in the context of pg_dumpall). Having
just gotten done fixing similar inconsistencies in pg_dump/pg_restore
for BLOBs, I'm not eager to re-introduce 'em for COPY BINARY ...
