You have a valid point, but if the only formatting issue you will have is tabs, then running `zig fmt` on your codebase is pretty much a non-issue.
If your project is small, just run `zig fmt` on the command line.
If you have a large codebase, you can just incorporate it into your build process (similar to how clang-format and clang-tidy are used in CMake projects).
But again, if you have a large codebase written in Zig, you've probably already configured your editor to run `zig fmt` on save :)
