The definitions in the OGL are in some ways superfluous. I've never heard of anyone being forced to "open" a rule that they called "Product Identity", and I've never heard anyone think that "thematic elements" can't be Open Gaming Content.

...IIRC publishers who want to use the d20 licence simply can't include an experience table in their books, or else the book wouldn't be legal under the d20 licence.
So yes, they could publish an RPG with the experience table from UA - but it wouldn't be d20, it would be OGL. And people have published OGL games with experience tables before - see the Everquest and Conan RPGs, to name just two of the most prominent examples.
So even an OGL experience table in UA doesn't really change anything about the d20 licence...
