We all read submitting-patches instructions (and many more). A need to
learn one more set of instructions for one more process leads to people
needing to learn 100 different processes for 100 different subsystems.

That's not the way how people should be contributing to Linux kernel.

The additional tag about kernel version is redundant and not helping
anyone. I doubt you apply patches on top of linux-next or top of
previous release (e.g. v6.8-rc1). Almost every maintainer applies on top
of current RC, so v6.9-rc1 currently, thus version is just unnecessary
obstacle.

Yes, that's what every sane person's workflow is. git format-patch -19
(cover letter goes from branch description).

Well, world is now using git as a standard. It's true there is quilt out
there, but even Andrew I think is going slowly towards git in some parts
of his workflow.

But then even Andrew accepted standard patch from the mailing lists. No
need for any other step, no need for any double submission (one public,
second to patches@armlinux or webform) with any other requirement.
