I disagree! .. Engineering is all about optimization, and using an ASR1k 
(which is being marketed as an "edge/PE router") in my edge doesn't mean 
that my network is not a "high-scale environment", it does mean that it 
fits my needs in this location, where other IOS-XR (ASR9k) fits in others. 

Plus, PCEP is no magic, Juniper's MX series starting from the vMX is 
supporting PCEP. They didn't claim that, a "higher-scale environment" is 
being required for this. 
I did not say that a high-scale environment is required. Just that as far as I have seen a number of deployments (e.g., 
Internet core/peering-edge) that are stating requirements for TE+PCEP are of the traffic scale that XR boxes are likely 
to be more widely deployed. IMHO, it’s this that means that XR is seeing the *first* implementations.

Some very large networks (including some that I have responsibility for) make extensive use of IOS XE, and hence there 
are also requests for PCEP implementations there. I encourage you to request it of Cisco too!
