I did the pre-1.0 language thing once with Clojure and don't really feel like doing it again, but I've certainly been keeping my eye on Zig because it has some interesting ideas. But this set of changes, even if it is still possible to wire it up yourself, makes me way less interested.
I'd recently been reading a bit more about zig, and even tried out using it as an easy way to compile c++ with llvm without having to fuss with system packages -- transitioning from c/c++ to zig was a major selling point
It just seems really abrupt, certainly unexpected. I'm not saying it's the right/wrong thing for the project -- just really really out of left field from my point of view
