Because it's essentially a large switch with an ASIC shoved up its arse? 
(run by a BU who seem to hate switches with ASICs.)

I'm assuming that the PFC isn't particularly adept at bRAS functionality?

I've never tried it, of course. Cisco historically liked to pimp the ESR 
for this job, though that was always ridiculously priced, IMO, for the 
job it did. I always tended to just use 7301/7201s, but recently have 
started to move towards the ASR.
