There are so many different approaches and optimisations (as you just
demonstrated in your message!). I don't feel this XEP is the right
place to document them, I think there is a lot of room for
experimentation. I want to leave implementations up to server
developers, deployments and (if the server allows it) client and user
preference. If good ones are found, they can be documented in separate
XEPs if necessary (and reference CSI).

This XEP is just about giving the server more information about when
it would be more appropriate to apply some kinds of optimisation.
