It's not the internals that I'm concerned about.

Well, I'd just like to see some thought about how this *entire* feature
ought to work, rather than just adding new knobs and syntax variants
incrementally and seemingly at random. Just because it happens to be in
the standard isn't really a compelling reason to make an overly-complex
part of the system even more complicated, IMHO...
