concur with Pauls assertions wrt "long tail".  Picking on specific RR types
to remove is a high maintenance method to put the camel on a diet.
Laudable but maybe not worth the efforts needed to clean up the installed
base.  Perhaps these two ideas might be a better way to simplify things.
1) remove additional section processing for any proposed RR types & then
rework existing rr's that require ASP.   2) dynamically loadable rr's types
(harder in resolvers but so worth the flexablity)

ymmv of course.
