Hi Bob,
Thank you for the feedback.
What we meant with that sentence is that there are different definitions of the Metaverse, even involving the concept of Web3.0. While we considered the notion of a persistent eXtended Reality. I think we can surely clarify better this point in a next revision of the draft.
In this initial version of the document, we already referred to some measurements presented in the following paper: https://dl.acm.org/doi/abs/10.1145/3517745.3561417.
This is a study of five popular social VR platforms and the experimental results reveal that all the tested platforms face fundamental technical challenges to realize the vision of Metaverse. In particular it is showed that throughput, end-to-end latency and on-device computation resource utilization increase almost linearly with the number of users, leading to scalability issues.
There are different proposals currently discussed in IETF (e.g. Media over QUIC and QuicR, APN, CATS,...) but it is not clear whether these solutions can solve all the issues. For this reason, we published this draft in IRTF (and not IETF) to recap the research challenges related to the concept of Information-Centric Networking, which can be seen as a common denominator for the Metaverse in the longer term.

Regards,

Giuseppe

I note in the introduction is says:

    "Metaverse" is a place-holder for a range of new technologies and
     experiences that is not particularly well-defined…"

based on that, I find the requirements listed in the next section to just be speculation.       Perhaps instead of speculating on the requirements and their solutions, it would be better to propose some work to do real measurements in some existing “metaverse” prototypes to better understand if there are any issues.
