Yes the site could do discovery on the identifier and get a landing page.  
However that would be self asserted and different from the verified URL for the 
openID.

It may be better but will be a different trust model.  That also applies to 
other relationships discovered in the XRD.  Anyone could point to my blog or 
Flickr in there XRD, however that proves nothing.   You could have trusted XRD 
with verified services but that is probably out of scope.

The security of openID is based on discovery and proof of control of the 
discovered resource.   That is what makes it different from SAML or WS-Fed.

When we start messing with the underlying model, we need to be careful that the 
assumptions people have built on top of that model still hold or we create 
security problems.

If the meaning of a openID identifier changes then we need to be carful that 
developers understand all of the implications.
