Since the argument name cannot be changed at the moment for backwards compatibility, it is better to update the docs. Maybe I could flag this for 1.0.0 refactor where making breaking changes like this would be okay. I do think using tokens as the argument name in all occurrences would be better.

Closing because fixed for now in #9940
