Where did Linus publicly state this was unnecessary?

Adding a reference to SeongJae Park's introduction of
scripts/deprecated_terms.txt or the like might help
make this list unnecessary if more terms are added.

I believe any existing code should not be changed,
not just code that is required to be maintained
for userspace.
