Allow individual permissions per channel like O365 Video allowed for. We don't need a mailbox, calendar, site, etc. created every time we create a Stream Channel, but we do have numerous instances where only certain users should be able to see the content of the channel. The additional items from an O365 group are not needed at all and it would tremendously help if we could create a channel and set permissions without having to worry about additional things being created that won't be used (like a SP site, calendar, mailbox) etc.
