I don't expect the review to take very long, but this is how it goes
with releases.  At some point, the release is cut, some bugs don't get
fixed, and you will simply have to live with them.

In any case, it entirely depends on how many ports it affects.  I have
the impression it is just a few particular ports having this issue?
