I think we're going to have to disagree there, then - yes that oneliner might reduce your LOC count and help you win at code golf, but it doesn't actually make things more readable and certainly isn't worth breaking from the rest of the community.

The ecosystem-wide consistency of go fmt is its biggest strength. Adding switches to disable features would eliminate that.

There is a lot more to effective code style than whitespace, and most Go code I've seen doesn't consider that, including the stdlib.

I've put a lot of thought into my style guide, and anyone who hasn't done the same has no useful insight on whether go fmt is a help or a hindrance.
