Thanks for the justification, it's helpful - however this doesn't belong
on the commit message so please remove that.

Please remove Reviewed-by tags that were not given on the public lists,
reviews should be performed on list (as per [1]).

The patch looks OK to me - however can you update the commit message
to better describe this (take inspiration from the examples you gave)?
And there is no need to make any reference to similar commits in the
history.

Thanks,
