In my day, the only ASR9000 we had was the ASR9001 client.

Try as we might, it couldn't be part of our BGP Add-Paths 
infrastructure. Not enough control plane resources to hold more than one 
full table in 2023.

While I imagine the Intel-based ASR9000 routers are much more powerful 
as a client, I agree that running a route reflector on compute is the 
best way forward.

Mark.
