They are being substituted by a generic fix implemented by the
following two  commits, so the user experience will not change at all
after the whole series get merged.

Or your point is that these two should come before the reverts? I
thought patchsets were looked at as an unit from the user experience /
functionally perspective. Can you please advise on what is the correct
approach here?

Thanks again for your review on this series.
