I would rather not (especially since this particular issue hasn’t been a
problem until now, and for only one package).  But overall it’s tricky:
some discrepancies are unavoidable.  So the real question is how likely
it is that package build systems and test suites will behave differently
because of these discrepancies, and often it’s really hard to tell
upfront.

I would prefer not to as this goes against the model where we assume the
build environment to be set in stone.

But I don’t know, we’ll have to think through it.

Thanks,
Ludo’.
