Khuzema:

We can add a Recommendation section to the draft.

Option 1 also uses XRO. I did not get your comment.

Thanks

Authors :

It will be useful to have a recommendation section in draft to clarify which options can be used in what scenario. Some discussion on comparison /critique of options would help.

For example :

Option#1 has scalability issue if XROs are not used resulting in crankbacks one after another. So if client layer cannot provide XROs, option#2/3 should be used.

Thanks
Khuzema
