Let me say back what I am hearing to see if it matches what you and 
other single level conformance folks are saying:

Conformance of ODF documents:

That an ODF document is "conforming" if and only if it meets the 
requirements and definitions more fully set forth in ODF 1.2.

Conformance of ODF applications:

That an ODF application is "conforming" if and only if it honors the 
requirements and definitions more fully set forth in ODF 1.2. That is to 
say an application can choose to do more than ODF 1.2, it could have 
photo processing capabilities for example, but it could not then claim 
to be ODF 1.2 conformant. Yes?

I agree with the first one. That is in part driven by my own view of the 
importance of file formats as part of the interoperability equation (a 
necessary but not sufficient part).

I do puzzle and hesitate over the second one. If I create an application 
that does everything required of it by ODF 1.2 and at the same time 
allows a user photo editing capabilities for images that are then stored 
in a conforming ODF 1.2 document. That is the resulting file is fully 
ODF 1.2 conformant. So, in what way is my application not conforming to 
ODF 1.2?

Or to put it another way, doesn't the greater include the lesser?

Or is there some other issue that I am overlooking?

Hope you are having a great day!
