Yes, this is not "secure" in the sense that it would meet IND-CCA.  After all, we are publishing the key in an RFC.  The point is to reduce this to a checksum.

The arguments about "encryption" all amount to a desire to make accessing the Retry more difficult for a casual observer.  Someone with a copy of the RFC will obviously have no trouble.
