Yes, that would be very nice.

You should note that not all resolvers work in the same way.  So it is
likely that tests may not work; i.e. they need a particular
implementation choice.

So, maybe, in the file include an option that enables one or more flags,
and if the current software product has this flag the test result is
ignored.

Anyway, this is not necessary today.

You can send me some sort of diff or patch or link.  And then I'll apply
it after inspection.
