i find that zig is too oriented at doling out directives for what not to do instead of just collecting and teaching variants of how and what to do. the lack of documentation on this interface is a sore case in point.
That's ok. "It's an unstable, experimental, early version." is a valid explanation. GP put the lack of docs and the new interface together, which... isn't an excuse.
You absolutely should expect documentation this early. The chances of quality documentation being added as an afterthought are not good. If proper documentation isn't part of the original goals after that time, things aren't looking well. Nobody is going to come and just write docs for months.
