Depends on your point of view.
One point of view is that the current ARM definition is different than
every other platform, and should be fixed.
I'm not enough of a C language lawyer to judge if the way it is
currently defined is "correct" or not; I'm just observing what common
idiom is/has been on other platforms, and having ARM an outlier is not a
way to get the most software on ARM. (having spent quite a bit of my
time making things run on ARM over the last 5 years, I know what my
personal opinion is: compatibility with other platforms more than
genuflection at either the C language specification or the altar of no
ABI change....)
