It's not a problem in itself, no. But it means that if you want to
obsolete only one of the two uses, you can't just mark the variable

It's not lightweight on the Elisp side where you need to add a lot of
extra code in ever more places to handle the special meaning of \r in
that rare case.

I think the fix is worse than the problem, personally.
