To quote from my reply to your patch 44:

   "Add this to the list of arguments for making this extension
   exclusive to core profile... which I have been saying since
   before a single line of DSA code was written."

I have been speaking my mind on this topic since Dylan Noblesmith worked
on it for GSoC *TWO YEARS AGO*.


This is not a new objection, nor has it been a quiet objection.
