We were looking at them for the same role as well, P router makes a lot of sense in places where the network comes together (for us often ahead of CMTS boxes etc) but routing is still required due to many paths being available. We are using juniper ACX5000s for this as well currently.

Particularly BGP free core and Internet-in-VRF. Single control-plane does not seem problematic, usually design should allow any single core node to be taken out of service without customer impact. Please talk to your account team about roadmap, what features are coming in which release in next 3 years.
