If tabbed indetation not being supported by the stage1 compiler is enough of a reason to not use a language it's probably best for zig to avoid those that would make this type of feedback and vice versa until stage2 and the language are stable (both support tab indentation, they just aren't finished).

I'm solidly in the tabs camp myself I just understand bikeshedding about this class of issue isn't what zig wants to/should be worrying about at the moment while core components are still being shifted around and written. In the meantime "zig fmt" runs as part of my build and life moves on.
