We constantly run into users who do this sort of thing,
and then yell loudly when their code breaks on a new
release. There is a VERY good reason to prevent this
sort of thing!

Note that the RM specifically allows the implementation
to be restrictive here:

4   The implementation may restrict the replacement of
    language-defined compilation units.  The implementation
    may restrict children of language-defined library units
    (other than Standard).

In GNAT, you must be an implementor to add children to
language defined library units. In particular you have to
obey GNAT style rules and use the -gnatg switch.
