So having them balanced and consistent would be nice. I agree that in
fixing this, bad things might happens. But surely that is a risk of
fiddling with any core part of Emacs. One response would be to not to
it. Another response would be to incrementally increase the number of
test cases Emacs has to enable this (and other) changes in the core to
be made with more confidence.
My response is that we should not do it until we have decent test
coverage of the insdel functionality. I simply don't believe in our
ability to avoid breakage in this core functionality unless we have
good test coverage. Been there, done that, have bruises to prove it.
