We discussed the approach on 2020's Unconference [0]. And there kind
of was an agreement.
Then I made a presentation on FOSDEM with all the details [1].
The patch had been on commitfest since 2019 [2]. There were reviewers
in the CF entry, and we kind of had an agreement.
Jeff Davis proposed a similar patch [3]. And we certainly agreed about cancels.
And now Bharath is proposing the same.

We have the interest and agreement.


Best regards, Andrey Borodin.
