That's a very bold suggestion to make. You obviously think you know all 
the possible uses of the web from now until eternity.
I'm suggesting that you don't. Millions of people use XML everyday. Do 
you really feel comfortable telling those people that they can't use 
those technologies on the web too?

I don't think that you know what the benefits are... that's why it's 
better to keep a open mind and give people more options for the future.

This is irrelevant. Developers can't use it now because of the little 
support for it. You can't use this as a signal that it's not needed.

What (little) benefit XHTML offered you in the past is irrelevant. The 
true benefits of XHTML will only be apparent when there is wide spread 
support for it.

How would you know this? Can you see what the world will need in the future?

Yes we do. It's not a HTML specification anyway. It's a HTML and XHTML 
specification. This is why the spec should never have been called HTML5.
