While such code might exist somewhere [tho most likely calling
indent-according-to-mode instead], the reasons why I think
breaking such code is the right thing are:
- it's very rare
- it should be easy to change this code so it works with the new (and
the old) convention, by replacing (indent-according-to-mode) with
(funcall indent-line-function).
- the reverse problem (i.e. where the restriction is currently obeyed
while it shouldn't) is much more common.
IOW the change could introduce breakage, but in my opinion, it will
correct many more situations than it breaks, and those that it breaks
are easy to fix.
