The NCS6000 was always designed as a core router to replace the CRS. We
just haven't seen the need for one since the CRS-X we run we operate
(8-slot chassis) is still more than enough for our requirements.

But yes, all of these edge routers, nowadays, are very decent core boxes
also, particularly if you run a BGP-free core and have no need to
support non-Ethernet links to any reasonable degree in there.
