Product A, B and C (3 columns)
for a defined set of features in a logical functional group

feat1  X _ X
feat2  X X X
feat3  X X _
feat4  _ X X

There is no interoperability between the different products even with a double implementation of each features. This might in some circumstances completely make the full logical group not usable. 

Having the full set interoperable add indeed difficulties, but is interesting for Web developers who are at the end of the food chain and have to deal with incompatibilities. There is a strong cost associated with the lack of interoperability. 

We might be able to leverage all of that with what has already been done in terms of testing. Sites such as whenCanIUse helps to figure out what seems relatively well implemented (even if lacking information in the details). Somehow I have the feeling that HTML5 is impossible to test without a large collaborative effort from the Web community. 
Maybe there is a need for NotUsableYet site identifying what's broken. The inverse photo of whenCanIUse
