(frankly, I would not have not supported __concat() at all). Also, overloaded operators should be programmed defensively, i.e. they should not accept arbitrary arguments (how could that even work?), but only those they can handle. If implementations adhere to these "rules", I don't see real issues.
Consider a type implementing some kind of list. Perhaps someone would want to overload the + operator to mean adding an item to the list. If the list accepts any type of value as a valid item, then you have an example of an unconditional overload.
