But HTML 4 was somewhat backwards compatible with HTML 3.2, while XHTML 2.0 is 
so incompatible with previous versions XHTML that it already received its own 
Namespace.

That's not true.
With CSS it is not possible to add the form, inline style, style element, link 
element, script element etc. stuff. Only tables, lists, paragraphs, block and 
inline formatting can be done via CSS. CSS Level 3 will add some of the 
missing features, but no user agent is capable of CSS Level 3.

It's not a good idea to send XHTML 2 as application/xhtml+xml to a user agent 
that says it accepts application/xhtml+xml just to present the user with an 
error message that the document type and document namespace are unknown resp. 
no default stylesheet can be associated with them per default.
