Exactly - the Metro will usually see 100's - 1000's of devices. IOS XE 
is nice and simple for such applications. In fact, Junos too.

For IOS XR, it's just too heavy for that sort of thing. Okay in the data 
centre where we are aggregating a ton of customers and/or Metro-E rings, 
but not out in the Metro. The Metro calls for a more agile OS. There are 
simply way too many devices to be dealing with the issue you mention, 
updating SMU's, rebooting, e.t.c., just to get a functionality and/or a 
bug fix from IOS XR.
