Hi, look here

https://github.com/ecostd/standard
this is not iso
also, subscribe to this group, then you get invitation to the monthly
meeting (not iso)
https://groups.google.com/g/cxx-ecosystem-evolution

and there is a ecosystem_evolution slack channel on the cpplang.slack.com

here, on iso, there is still the WG15 mailinglist, not very active but from
time to time there are topics

hope that helps
