Call for objections: deprecate postmaster -o switch?

We had a discussion in late September about deprecating the postmaster's
-o switch in the 7.2 documentation, with an eye to removing it in 7.3:
see thread starting athttp://fts.postgresql.org/db/mw/msg.html?mid=1036935

It wasn't entirely clear to me whether everyone had agreed to the idea
of marking -o deprecated in the 7.2 docs, so here's your chance to
object if you think it's a bad idea...
