But so what? It still doesn't remove v4, in any shape or form, and if that was proposed to the kernel, I'm again fairly confident it'd be rejected.
> I also see hostility towards IPv4 in the comments here and other similar discussions
Ah, yeah that might be. I just saw your comment first, with no context of what you were actually answering, so it kind of looks like you're replying "to the submission", which really isn't denying any freedoms, I guess I was confused about that, my bad. Still, wouldn't it be better to answer directly to those comments, rather than "replying" to an argument/debate that is actually happening elsewhere?
The reason that I don’t like seeing patches like this, even as a “joke”, is that there are real people who would like to see IPv4 removed (possibly by government intervention) in order to achieve their dream of an IPv6 only internet. The whole idea is preposterous, but here we are. It’s about as realistic as banning cars but that doesn’t stop the endless flame wars about it.
Someone has to step in to point out that v4 and v6 were designed to coexist, this is fine, please don’t remove common standards for your personal preferences.
I have no problem with allowing optional IPv4 or IPv6 only builds as long as both are kept well-maintained.
