Well, I don't think rolling up the miscellaneous commands into a single
binary with behaviour dependent on arg[0] is a bad idea. I don't think
it's something to be looked at during feature freeze, though, especially
given our backlog. I think we'd need a good long lead time before we
removed the old names from our default install - at least one release
cycle, so it would be two years or more before this became any sort of
reality.
