Ummm, you're mixing two things there.  The *language* is suitable for
embedded systems.  The language does not dictate anything about where
things are stored, and nobody is asking for the Ada standard to
require that every Ada implementation be able to allocate every large
local array it sees.  Not every compiler that compiles the language
will be suitable for embedded systems, but that's not a bad thing---
not everyone who uses an Ada compiler is using it for embedded
systems, and those that aren't shouldn't mind if their particular Ada
*implementation* does things in a way that's not suitable for embedded
systems.

I don't see a problem with a compiler generating code to allocate
arrays on the heap that it knows will be large, or supporting a pragma
that tells it to put arrays on the heap.
