True enough, but the point of the AI is to introduce a specifiable
attribute to provide some control over this. Which is enough for most
applications (of course, hetrogeneous networks need to go beyond what
the language can provide). I suspect that you are thinking about the
recommendations about the default base type representation (which GNAT
indeed always has supported), but the AI goes beyond that (and indeed it
was always intended that it would do so, it's just been waiting for
Tucker to write the proposal up).
