Well, yes, in theory. However, in practice, I think that what was intended was
actually achieved. Do you remember Pascal compilers wherein the deviations were
of the form "I think feature X is inefficient or hard to implement, so I
modified the syntax and semantics to give you feature Y and no other compiler
did it the same way." Of course, Pascal was a fairly simple language, yet it
still had deviations from the "standard" definition in most compilers. More
complex languages were worse.
What we have today is a case where compilers purporting to be "Ada Compilers"
don't do screwy things like not implement Tasks (because its too hard) or change
the memory allocation/deallocation scheme from new/Unchecked_Deallocation to
some other scheme like mark/new/delete (because its more efficient). Sure, there
may be missing annexes and you may find some corner-case in the language that
doesn't work right, but mostly you get the full language. At least I know of no
important exceptions.
I think that's a useful improvement that Ada brought along and ought to be a
selling point because AFAIK, C++ is a long way from this goal.
