Huh, I guess this is just a case of pkgs.alpinelinux.org not being updated yet?

Yeah I just 'gambled' with the URL, weird that it's still not there. Seems like the same thing happened last time around:

I did look at edge and figured as long as it still appears there, it will likely still be around in the stable releases.
