That sentence would be one strong argument, I am not sure why you are saying
that it is grammatically incorrect however.  Remember that for the JOSE working
group the following is a key agreement algorithm - ECDH-ES+A128KW.  This
composite algorithm does do an encryption operation and not just a key wrap
algorithm.

This difference of opinions is one of the reasons why key_ops needed to be
defined, to get a much finer view of what the operations were that were
associated with a key.  You are thinking in terms what what it means for the
algorithm "ECDH" and there is no such algorithm in the JOSE world.

This we have the sentence that explicitly states it to be true and we have an
explicit example of the usage in the document.  I think that is good support
for the thinking of the JOSE document editors and working group.
