Obviously not, if there are no listeners :)
I agree with your point, however AFAIK there is no actual place dealing with this specific case.
This even is now being triggered from ```eZContentCacheManager::clearObjectViewCache()```, however this does clear object view cache which would be unnecessary / plain wrong in this situation.
(Legacy does not really use/care about 'uri' cache the same way SF does)

Any suggestions for improvement are welcome, though...
