Hi James,

I'd like to check in on what you said in [1]. It sounded as though you were
planning to look at the assignable counter work from an Arm/MPAM
perspective but that work has since progressed (now at V11 [2]) without
input from Arm/MPAM perspective. As I understand assignable counters may benefit
MPAM and looking close to settled but it is difficult to gain confidence
in an interface that may (may not?) be used for MPAM without any feedback
from Arm/MPAM. I am trying to prevent future issues when/if MPAM needs to use
this new interface and find it confusing that there does not seem to be
any input from MPAM side. What am I missing?
