Hi Robert,
could you please clarify why you believe that ioam "is just control plane
on how to handle a slice"? Do you believe that support of RFC 9197
<https://datatracker.ietf.org/doc/rfc9197/> does not command any change in
a respective data plane and can be achieved with a common extension(s) in
the control plane? Also, could you kindly explain how IOAM Trace Data could
be collected?

Regards,
Greg
