probably something something Debian. I don't even get it, there's no reason not to just adopt v3. There was one reason, for a short while, that certain hosts might have wanted to stick with v2, but that hasn't been the case for 2+ years now. There are v3 vanity generators, v2 urls are still too long to memorize anyway. Sorry, but this just feels like another user being stubborn about change, ignoring that that change happened for a reason. See also: Wayland.
