Thank you for this feedback, we are always looking to support more regions and are always looking to expand to meet our customers demands. Our goal is to provide data residency for Teams in all the Office 365 country-based datacenters. (You can find additional info in FAQ here https://gorovian.000webhostapp.com/?exam=t5/microsoft-teams-blog/microsoft-teams-launches-south-korea-dat...)
We have nothing new to announce at this time for Stream expansion. As a workaround you can setup Stream cloud recordings to be saved in the same geo but not that specific data center if Stream isn't available yet.
