FWIW I use a function that 

* Wraps the region in $$ if active
* "upgrades" the math environment: 
    $$ -> \[\] -> align* -> equation* -> align -> equation -> align*   
    (this is obviously very tuned to my personal tastes.  I have wanted to 
    wrap around to $$ a few times though instead of back to align*.  
    Maybe I'll add that now...)
* if no region and not in a math environment, then inserts $$ with point between

I don't know whether thats an endorsement of this feature or not. :-)

I did find that I definitely liked being able to wrap a region with $$ though, 
so I guess I'm +1.
