Not for much longer [1].  And no, I don't believe that that patch
makes any noticeable difference in the code's robustness.

In the end, a bug affecting these considerations is a bug to be fixed
once it's found.  Building potentially-themselves-buggy defenses against
hypothetical bugs is an exercise with rapidly diminishing returns.
