wow, I fear that would be pretty insane in some situations. Let's take 
the infamous community example again...
Imagine a "small" community of 50k users like typo3.org, there's a page 
displaying the profiles of the users, now whenever someone edits his 
profile ... boom 50k pages to rerender ... probably not a good idea ;)

However, the new caching framework was brought to the core exactly for 
these situations. Remember you can tag cache entries to in the end 
selectively clear them. I think that's the way to go here.


all the best
