The proposal makes a different design choice, in saying that you need more than just a 200 OK response to say, beyond all doubt, that a URI refers to something that is member of Set-B.

Really simple question: what does 200 OK actually imply?

I know it to mean the following:

Client to Server via a Locator (a URL which is a kind of URI): GET me 
*data* from Location/Address X.
Server to Client: OK, I'll retrieve the *data* requested from the 
Location/Address specified in your request.

If you use a Locator as a Name in the generic sense, then the protocol 
works as follows:

Client to Server via a Locator (that isn't actually functioning as 
Locator anymore): GET me *data* from Location/Address X.
Server to Client: See Other, because I can't retrieve *data* for you 
from the Location/Address in your request.

Simple, elegant, and seriously dexterous. All alternatives ultimately 
deliver a downgrade because "deceptively simple" != "simply simple".
