If you know you haven't finished, you may use WIP (work in progress)
instead of RFC in the title.
I wasn't familiar with this tag. I will keep it in mind. And this is not
included in Documentation/SubmittingPatches , so I will send a patch to
include WIP tag.
Please don't. It is OK to say WIP or RFC or some people even say
[not a patch] there; we do not need to enumerate all of them, and
your original RFC was just fine.
