I'd say we likely shouldn't be putting significant effort into adding 
**new features*** *into 5.2.  I'd recommend adding it into the 6.0 
branch and if/when we decide to consider a 5.3 branch release as a 
further stepping stone to 6.0, perhaps we back-port this feature to that 
branch if the team feels its relevant to do so.

But that's just my perspective :).
