This isn't a situation like (say) peephole and peephole2, or even text
and RTL prologues, where there's a major conceptual change, or where
major code needs to be kept around to support the old and new way.  A
few remaining uses of the older interface don't seem to be a major
impact to me.

I don't mind saying that we'll try to do this if we have time, but I
don't think CodeSourcery can make a firm commitment.  Like everyone
else, we've got a lot on our plates, and this project has taken a lot
more time than anyone expected.  So, broadening of its scope isn't
something that we can definitively commit to.  I would hope that the
community would accept the major structural improvement, even if it is
not a 100% complete transition, and that we can then work on any
remaining conversions in the fullness of time.

Thanks,
