The actual URLs are generated through the UriBuilder in Extbase [1]. In 
the uriFor() method the cHash is disabled if the target action is not 
cacheable (since Extbase 1.3).
I already experimented with a solution that only removes the cHash if 
target action is not cacheable *and* the target page is not the same as 
the current page. But that behavior is not very transparent IMO and it 
probably doesn't cover all situations.

So, I agree with Franz: To solve this cleanly, we probably need to 
extend the caching mechanism in the core.. Until then I would revert the 
feature as polluting the cache seems to be the lesser of the two evils.

Or do you have an idea?

Best,
Bastian
