I like Paul's suggestion. It's easier to have the core work in there
and easily available
for everyone to work on, than to try and create one perfect patch.
It's also then easier
to track what follow-on bugs have been fixed in 8u.

Does the initial patch allow this to be disabled? The risk is
significantly reduced if it
is still possible to build as now with it applied.
