Are changes in this file necessary to make the tests pass? (Or do they have another purpose, like perhaps making this function more consistent with other arrow join implementations?)

It makes the API consistent with dplyr, but not necessary to make the tests pass.

I'm ok with that change; however, I think it should be consistent for all of our join wrappers (anti, left, right, etc.). Currently they all define the suffix argument explicitly (and I think the default value of c(".x", ".y") is necessary and may result in an error if you try to semi_join overlapping columns?).

I've removed this change as the anti_join() signature is also different to dplyr's. I don't quite understand what you mean; please can we discuss this in #33709?

Is this change intentional?

It's the consequence of running the styler.
