We don't need to have the blocklist anymore, but using hid-ids.h is
still used, and sometimes has the benefit of raising eyebrows when you
add support for a new device and realize that it was already defined.
So keeping the list around is not so much of a bad thing.

We are definitely in the bikeshedding phase, but I would leave the
code as it is in this patch :)

That change-id should be dropped, it has no meaning to us.
