Since Ard is on holiday until the GetTogether, I'll try to answer this 

The reason is, as Ard said, to make it less error prone. People easily 
make mistakes if they have to build a cachekey string themselves, en 
they also easily forget to actually put the jx:cache-key and 
jx:cache-validity attributes in the JX template. I am talking from 

It also makes the code more readable/transparent/explicit, because you 
don't need the extra flow step anymore in many cases.
