Me too. I really have no idea. Felix Nagel also reports[1] that he does 
not get a 404 when omitting the cHash while required parameters are in 
the URL.

Can you try to debug this? Or at least try with a blank TYPO3 installation?

What happens is, that additional page cache entries are written, which 
would not be needed, as the plugin itself is uncached. Other than that 
no other negative effects are to be expected.
