As JohnB mentioned, it is just an additional layer. If the RP supports only
the conventional one, it is fine.
If the RP supports it but if OP does not, the RP can find it out and falls
back to the POST binding.

Could you kindly define what you mean by "relatively narrow"?
If you think it is only the proposers who wants this feature, you are
mistaken.
Also, from the implementation side, it is not that complex.

Frankly speaking, I think OpenID will die if we do not support this kind of
feature because it is not viable in the mobile world.
