Re-rolled a v5 to address that discussion:
https://lore.kernel.org/git/cover-v5-0.8-00000000000-20211101T190630Z-avarab@gmail.com/ (local)

Per the re-roll the discussion doesn't directly affect this series, it
was on a part of the commit message that's musing about some WIP/POC
code I wrote, and which might use the new interface added in 8/8 in the
future.

In any case, I updated the commit message to note the potential issues
with that WIP code that were raised.

But as far as this progressing (aside from the rc period & all that) I
don't see why it should be blocked on that.
