It's true that, as a pre-1.0 language, choosing Zig means taking on the implementation burden of changing code to keep up with language changes. But it's already being used in production in a surprising number of places.
Wanting to wait until 1.0 to get started is a respectable choice. I prefer to get a head start, compile against master every few weeks, and change what needs changing.
At some point it becomes a bit ridiculous to be pre 1.0 for nearly a decade. It is symptomatic of a level of complexity and confusion about the core language use cases* that is a nonstarter for me.
* In other words, I think it's trying to do way too much and would have benefitted from aggressive scope reduction years ago.
