We could remove it, but then what we have wouldn't really be a release candidate anymore, so the release would get delayed.
How long do release candidates soak in the field before being accepted?
For this release, the release schedule is defined in PEP 375
I'm curious if an exception could be made in this case, given that you have admitted that ipaddr is not an important library.
This would be need to be decided by the release manager. However, given that Guido has already pronounced on this issue, Benjamin is unlikely to change anything.
You seem comfortable with these quirks, but then you're not planning to write software with this library. Developers who do intend to write meaningful network applications do seem concerned, yet we're ignored.
I don't hear a public outcry - only a single complainer.
