Comment (by simonpj):

 I think that the underlying difficulty is that we don't have a clearly-
 articulated protocol.  What, step by step, should a GHC developer do when
 adding an extension?  The steps should cover what happens in the
 intervening bit, when the extension isn't in Cabal but is in GHC... we
 don't want validate to fail at that point.

 I think if we laid out some steps (and pointed to them from the test) it'd
 be much more likely to happen.

 Thanks, Simon
