Here's a few:


The problem has been known for four straight releases. I say it's time
to fix it, before F17 becomes the fifth.

+1 for considering IPv6-only significant.

The lack of out of the box support for IPv6-only is really killing any
possibility migrating away from IPv4 in our corporate client networks,
where we have a "bring your own device" philosophy (we don't centrally
manage people's laptops and therefore can't change bad defaults). We
really need to get IPv6 deployed, as we are running dangerously short on
IPv4 addresses - it isn't easy to get additional allocations from the
RIPE NCC these days, either (and in a few months it's expected to be
completely impossible as they'll have none left).

The patches required to actually fix this problem exist and they really
are trivial and non-intrusive. It's not like finally fixing this problem
will delay the F17 release in any way. Heck, I'd wager that the time
wasted on this very thread and the related bug reports are orders of
magnitude more than the time it would take to actually apply the patches
and be done with it.

Yes please. Besides, you promised as much in the F12 release notes...
