That would be persuasive if there were some compelling reason to treat
"give me an unspecific value" as special in the FFI.   Since there
isn't, it isn't.

You're saying "Well, I chose to make a special case of UNSPECIFIC for
reasons I haven't cared to get into --- but my decision is just fine
because surely you can hack around it in your implementation."
