Metadata is supported in any HA supported protocol. Your concern is what?
but as the Matter standard doesn't yet support energy monitoring, users are limited to basic features like on and off and scheduling

Granted the article is almost a year old. But I just didn't realize that Matter now supports energy monitoring. Somehow I just missed that news.
It looks like it got added in the protocol V1.3 and then further refined in 1.4: https://csa-iot.org/newsroom/matter-1-4-enables-more-capable-smart-homes/
Yep just saw that too after I researched it a bit more. What is strange is I don't remember Eve Energy having a firmware update since then. Makes me wonder if they had it ready to go in previous firmware versions based on internal specs they saw? Or maybe I just forgot about a firmware update I did.
Matter itself is different from data passing through HA.
