Peter - Is there bug reports on each of the issues you're referencing. It
may be best to ensure that there is and continue the technical discussion
on each on their own merit (case by case). This could be a deep rabbit
hole, but slowly tackling things point by point is probably the only way to
end up with a positive conclusion.

A different way to view this - If your opinion on what's technically best
and what they view isn't aligned and they will block you overwriting their
approach - try to see if an alternative can co-exists and introduce it as a
flag. UD is such a religious argument that disagreements are bound to
happen.
