No, the ETag does not need to be part of the URL: it's a separate component of 
the protocol.  A client can use a conditional GET with an ETag to get either the 
latest version or an indication that the client already has that version.  That 
is how a client can know whether the server has a new version without putting an 
explicit version number in the accessing URL.

Sorry, I'm not following this.  Are you thinking of a scenario where the client 
has a more-recent version than the server?  That's a problem, I suppose, but 
it's not a problem tzdist should try to solve.
