There is one special case where being able to add advice to more
functions, especially some primitive ones, accessibility. At least two
packages written to make emacs accessible to blind and vision impaired
users achieves this through advising functions. Currently, there are a
couple of places where accessibility is limited because of the problem
of advising primitive functions. So, adding this ability would likely
benefit at least one group of users and do so without any issue for
other users.
