This seems like asking for trouble, too, although I guess it depends
on what you mean by "be careful" and "specify". I can imagine bugs
potentially sneaking in when somebody makes a change to GHC without
thinking about ExtCore (which is exactly what happened in the past),
but I suppose that it's possible to implement some sort of
ext-core-lint phase or something that checks that the ExtCore that GHC
is generating is consistent with the specification. But, you would
want to make sure that that phase was actually enabled when the test
suite gets run.

Cheers,
Kirsten
