This sounds like a solid idea.  I'd suggest making it an option on the 
strategy.  The same option could indicate that existing features should 
be clustered on activate.

As I suggested on the ticket, there's no need to loop through existing 
clusters.  The strategy has a reference to the original features 
(strategy.features).  As long as clearCache is not called in deactivate, 
those features will still be around after deactivate.
