I've just went through my inbox to make sure I didn't miss anything
but, barring some undelivered email, the only thing you ever stated
wrt this series (other than your general dislike of the BIT() macro)
is this: https://lkml.org/lkml/2021/1/27/202 four versions ago.

It's Linus Torvalds who stated he'll need an Ack from Al and I have
Cc'ed him on multiple iterations over the course of several weeks
after that. I assume he's got more important things on his plate but
there's not much more I can do...

Feature creep is an exaggeration IMO for something that the very
maintainer of configfs (Joel Becker) defined in detail in the
documentation a long time ago. Most likely the need for committable
items was clear from the start but as there were no users, no
implementation ever followed. Now we've presented a very clear
use-case hence the proposed implementation of the concept designed by
Joel.
