Agreed.  I also see the similarities, but I don't think there is 
enough overlap to cause problems, so +1 from me.  My only suggestion 
would be to consider whether it makes sense to slightly widen the 
scope, since I believe Watcher operates in the very similar area of 
optimisation, and to me auto-scaling just sounds like one particular 
use case out of many different approaches to optimisation, of which 
Watcher covers several.  So for example you could call it the 
"self-optimising SIG" ;-) 

Feel free to copy any of the self-healing SIG's structure if it helps!
