Thanks everyone.

Just a small note that there is a mess up in Peter's series that he is
already aware of: patch 6/8 depends on 8/8 so there is either a small
refactoring to do or change the order of the patches.

I also have asked Peter to look for regression tests in hid-tools[0]
before I can merge this. FWIW, I am putting together a CI system that
will run this test suite for every submitted patch (plus a few other
tests). But the test suite simply lacks basic wheel testing, so it's
hard to see regressions :)

I should be able to apply the series in the next following days or
next week I think.

Cheers,
Benjamin
