Well, I think Linus was saying that we have to do both (where the
signal interrupts and where it doesn't), and I agree with that:
There are enough reasons to discourage people from using uninterruptible

Fortunately, although the -ERESTARTSYS framework is a little awkward
(and people can shoot arrows at me for creating it 15 year ago :-), we
do have a way of supporting both styles without _too_ much pain.
