We have a big user community and what _you_ want for this feature is
only a small part of our decision on what is needed.  Robert's concern
that this might not be useful enough for the general use-cases people
want is a legitimate, if difficult to hear, analysis.

The resistance we get when removing features is sobering.  Imagine the
worst case, e.g. xml2, where we rightly implement it later, but there is
something that is better done with the old interface, and we end up
having to support both.
