Yes, but the hypothesis in the initial post was that the recipient knew
or suspected the key ID out-of-channel -- which is a wholly plausible
hypothesis.

I happen to have 9 secret keys on my current keyring. If I were to
decrypt a lot of message with thrown key IDs, all in one shot -- say I'm
searching for something in my mailbox, and I get a lot of messages from
a particular person who throws IDs when sending to me -- that actually
could be significant computational savings.
I don't think this is useful in the common case, I only suggested it for
the rather rarer case of bulk processing, because it seemed like a small
change that was already suggested by the documentation.
