Thanks for your comment.

Although we believe this is a good idea, we fear breaking legacy
server-side applications (e.g., yahoo maps), since although the client will be
changing its behaviour it will still be talking to the same servers.
Further, you do not want to have to have server side applications arbitrate
based upon the type of the user agent submitting the request.

However, in order to promote application interoperability, the working group
has
decided to require (MUST) that user agents that do not support maps return 0,0.

While it is true that this does not allow you to distinguish between supporting
and non-supporting user agents, at least you are guaranteed to get something
back.

Best wishes,

Steven Pemberton
