This regressed back in https://github.com/ziglang/zig/pull/25154. I didn't get around to fixing it until now, so a few instances of the warning snuck into the repo over the past few months, which were fixed in the previous commit. The regression has not appeared in a tagged release though, so this is not a breaking change in 0.16.0. Resolves: https://codeberg.org/ziglang/zig/issues/31049
