While I agree that specifying <content select>, distribution APIs, and
<shadow> is relatively simpler than some of the other parts of the
spec, I'm pretty worried right now about the performance of those
features, especially for dynamic changes. I just found out, as well,
that Mozilla's XBL implementation of these features worked correctly
in the static case, but is completely wrong in the dynamic case, so we
don't have any real data on how slow doing that stuff correctly is.
