Other languages debate for years, because they have a customer base with important applications into production that don't find funny that their code is broken with experiments.
Zig is years away to become industry relevant, if at all, of course they can experiment all they like.
I think it benefits the overall ecosystem for them to experiment so other languages can take what works
Obviously, that comes with the language being in beta. If you don't want things broken, use a complete language.
