Yeah, I tend to agree.

Once your users (you as a script writer) have an option to set the
configuration to participate in the tree-wide party early, you would need
to update your scripts immediately so that they don't break on them; so
the introduction of the configuration becomes a flag-day event.  Hmph...

Yeah, I think you convinced me that an elaborate configuration wouldn't
help us at all.  We just keep warning in 1.7.x series when "add -u" didn't
see any pathspec, and flip the default at 1.8.0

Simpler and cleaner ;-)
