It has been the "gold standard" to scale the routing domain since about 2003 (or maybe even earlier; I only started teaching about it in 2004). It's a design principle that has worked well and stood the test of time. Perhaps the only challenge I am seeing now is as we run MPLS in the Metro-E Access, where some vendors deploy very tiny FIB's (think 20,000 slots on the ASR920, for example), there is a risk of exhausting those due to IGP and LDP state. I've often found 3107 to be quite complex, and when we get to that stage, I'm hoping to find a cleverer way to deal with it before the MX204 becomes the Metro-E gold standard :-). Mark.
