A good point. I'd say it's more that the relationship expressed by the verb may go either from subject to object or object to subject, depending on context, and with a subtly different meaning depending on which direction it goes. I certainly don't see it as its own antonym—either way, it means some sort of inclusivity. It's a really useful and economical word, which is why I'd hate to see it fall (even farther) out of use owing to fears that it will confuse the "to be comprised of" crowd.
