Hi Dmitry, 

you are right that this is the design of the cHash. That's the way it works.
Nonetheless a given design can have missing features. The cHash mechanism
has many missing features, because it works only on the level of the whole
page insted on the level of components.

The caching behaviour of T3 is limited. This limitation is a blocker for
some usecases of today, where companies decide for competing systems. To
make the caching behaviour fast and flexible should IMHO have much more
priority. There would be some options already for the 4x branches.
