I’ve yet to find tooling that supports this. Clang format has a setting that looks like it does it, but actually does something else. If I have to press the spacebar a bunch of times each time I add an argument to a function, that’s a pain, and it’s a bigger pain to convince the people I’m working with that that pain’s less bad than using spaces everywhere and having the IDE deal with it.

Until the people making editors and auto formatters acknowledge that the obvious most sensible whitespace style is even a thing, I’m forced to do something else and be really grumpy about it.
