IIRC, the reason why serializers are "special" WRT cache stuff is 
exactly this (i.e. circular reasoning alarm sounding): they are not 
depending on the environment, and they act as blackboxes.

OTOH, the environment-dependent serializer will need to provide the 
right Validity for the cache and that's it. Am I wrong?

It looks to me that the issues are mostly potential abuse/Separation of 
Concerns, and I think they are obsolete by now:

* People could write pipelines of just generation -> 
specialSerializerForMyUncleBrowser, subverting the whole architecture 
(but they should not be using cocoon for this, there are simpler ways to 
shoot yourself in the foot) ;-)
* Also, overoptimization in the cache layer (you wanted to asume 
serializers are ergodic, to save the dual caching and avoid potential 
performance problems, since some serializers *are* expensive)
