Didn't someone else have a similar use recently? Controlling some
supply external to the system. I can't seem to find it now.

In any case, it's not for you to describe, but Naresh, and in the
binding and commit messages. But first we need to overcome proper
usage of get_maintainers.pl. In response, to my first reply on v4, I
have a second v4 sent privately today (and still only the vendor
prefix). Sigh. AFAICT, for v1-v3, the only thing that made it to the
list was the cover letters. Bottom line is this series has multiple
problems and shouldn't have been applied yet.
