New enhancements in Private Channels in Microsoft Teams unlock their full potential

I wonder if this will allow the use of all the Microsoft apps that aren't currently available as tabs in private channels (e.g. Planner)?
And whether the Groups will appear individually in Entra or as linked to the patent Group?
I just wish private and shared channels adopted settings from the parent Team / SharePoint site, such as Member settings, sharing (e.g whether Members or only Owners can share externally from the Group), and file tab views (as we add version and file size for every Team)?
