I'm not sure I agree with the title of this bug.

Sure, it'd be easier to program with a map and set that did a ref/deref on its
keys. But there are at least two other solutions to problems at any individual
call site:

    1) Add code to remove the string when it no longer should be in the
collection. That code can be run by the owner of the string.

    2) Add explicit ref/deref.

These are both possibly tricky to get right, and may be inferior solutions to
the problem. But I generally would prefer not to name bugs after a particular
solution to a problem.
