Summary: NSTokenField needs some sort of tokenField:willDeleteObjects: delegate API.

In that project, I had to implement controlTextDidChange: and go through the contents of the field editor string just to figure out if any tokens had been deleted upon user edit. I needed to do this because, for this token field, duplicate tokens are not allowed.
That's an unfortunate step, potentially fragile, that could be avoided if the token field would *tell* its delegates when it's going to delete tokens.
