Agreed,
not only that but having 2 separate patches also means that the bug
that was fixed by the commit being reverted could reappear during
bisection.

More generally I think reverts should be reserved for commits that
later turn out to be wrong or unneeded (ie should never really have
been applied).
If they were OK at the time but later become unnecessary due to other
code changes I think all the related modifications should be done in a
single normal non revert patch.
