Well, I doubt that would be very popular with anyone that has existing Ada 
code that they want to use with the latest version of the language.

As Robert Dewar says, incompatibilities have a very high bar. There has to 
be real and compelling value for an incompatibility. I don't see that in 
this case that that it not clear that the revised situation is really better 
than the current one -- it's mostly a sideways move.

That's pretty cynical. Most of time, once you get your generic working, you 
hardly every touch it again. Besides, you could make the above statement for 
almost any Ada (or other programming language) code when it is reused.
