We do have plans to improve delta.

Please explain why you want to put a better top form flat into gcc, but not all
of delta?  And then if it is properly part of delta, I think I might rather
that I just shipped it with delta and that you pointed at delta.  Why should it
go into the gcc distribution?  And if so, perhaps 1) we put the new top form
flat into delta, and then 2) you just distribute the whole new delta with gcc,
as an embedded but semantically distinct project?
