I think that's one of the best contributions golang has made to the programming world. The idea that the language itself should be easy and unambiguous for the compiler and the human to parse. And that a single formatting standard makes life easier for everyone.

If we ever move beyond using text files for storing code, we could eliminate formatting differences entirely... but efforts in that direction have run into many issues in the past.

Except the go standard is awful, so a language-wide formatting requirement with bad defaults makes the language basically unusable (since programs are made to be read, not run).
