As is often the case, I'm a little more positive about including this
than Tom, but as is also often the case, I'm somewhat cautious, too.
On the one hand, I think it would be cool to have and people would
like it. But, On the other hand, I also think we'd only want it if
we're convinced that it's a really good implementation and that
there's not a competing design which is better, or even equally good.
Those things don't seem too clear at this point, so I hope Jeff and
Joe keep chatting about it ... and maybe some other people who are
knowledgeable about this will chime in, too.
