There's an alternative of being much more up front about the status. For example the project page doesn't really say it's unstable/experimental. It only says "Zig has not yet reached v1.0" on the "getting started" page, which doesn't really mean that much - for example Putty is still at 0.83 after 26 years.
If the project invites me to use it "for maintaining robust, optimal and reusable software." without putting "super unstable, we don't even care about docs" on the same page... that's also saying something.
