Really? Where exactly is the loophole in 'If the question relates to a
contributed package ... try contacting the package maintainer first.'?

I don't see an addendum that states 'But if you are not 100% sure that
because of course those people know WAY more about the package and its
contents than the maintainer, who is really just tangentially involved
with the package and probably couldn't clear up any misunderstandings
you may have.'

But I could be mistaken. I am not good at reading between the lines...
