| If '>' with set -C is not atomic, then it cannot be relied on to perform

Depends what you believe "this function" really is - but it certainly is
not avoiding race conditions when two processes are attempting to create
the file at the same time.
What -C is (or should be) really for is avoiding accidentally writing
on top of (long existing) stable files (particularly ones that are hard
to re-create).
A non-atomic -C works just fine for that.
