Ouch, that would break everything and no UA would agree with such a 
descision. Making even more tag soup hacks would be very bad for the 
real world.

Why would you replace text with an image here?

I assume you mean backwards compatibility as the HTML4 specification 
states how this should work.

I think MathML is an excellent example of something that is easy to 
introduce in XHTML documents but near impossible in HTML documents 
(although you could use the OBJECT element with the data URI scheme).
