You're welcome! It is great to see people already using it. :-)

Could be -- I took a look at several places and to the official
guidelines; but I am sure I may have missed some things :-) For some
options where I was unsure, I ran it through several "popular"/common
folders and see which one generated a smaller git diff -- maybe you
can try that and see what you get (also, it would be great if you can
try some others outside kernel/*).

It went through Andre the first time. In any case, I think it is fine
to send it through any one.
