Babu: It is difficult to start drilling into the implementation before there
is agreement on the interface. One reason you went through the effort of
the first few iterations was to accommodate Arm's use cases as we understand
it, but we need to hear from Arm if we are on the right track here.
I do hope that we will hear something in the next couple of weeks.

Dave: Could you please check in if the interface introduced [1] is something
of interest to Arm? If it is not, we can proceed with the implementation without
trying to consider how Arm may use/need such an interface. If it is, could you
please let us know when we can expect feedback from Arm?

Dave: fyi ... there is a similar scenario with [2] that aims to address some Arm
feedback ([3]). Do not be deceived by version number of [2], which is categorized
as a "new approach" aiming to accommodate feedback. It has a long history [4].
