Maybe different test name?

I'm not sure about including the tag itself in the check, as that is already covered in the original buildtag test. We don't normally say that a tag inherits from itself, but maybe this makes sense anyway?

I'm curious if we have any hypothetical cases where someone would use this test and want/not-want to also match against the tag itself. In the MBS case that inspired this, I don't think it matters.

Maybe different test name?

I originally suggested something like "buildtag_inherits_from". If we were to go with that, I think that would definitely change the expectation to not match the buildtag itself.

Ok, with renaming it makes more sense to not include the buildtag itself. And it is simple to write rule 'buildtag or buildtag_inherits_from' if anybody wants. I'll change it.
