I always found that "feature" annoying because students who knew the material well could fail questions testing its mastery due to imprecise instructions. (My personal pet peeve is not making it clear whether "or" is inclusive or exclusive.)

I can't think of a situation in which "or" would ever be used in an exclusive sense unless it was explicitly called out as an XOR or included "but not both".

"Is it A or B?"

"Do you want the burger or the ribs?"
