Let me dig further into this. I have never had any reason to 
believe the ASR1000's would forward traffic in CPU, unless 
of course for the reasons that IOS XE is based on IOS.

I know that new platforms which are being released, based on 
IOS, still forward traffic in the slow path if the FIB is 
full, e.g., the ME3600X/3800X.

Will let the list know what I find out.
