Is OneNote better for cooperation than Loop now?

Just noticed that we can't open Loop inside Teams any more. We have configured the loop workspaces as websites than used to open in the tabs in the individual channels. Instead it opens in a seperate web browser now.

OneNote on the other hand, still opens and works fluently within it's respective channels.

I understand that it's a security issue that have moved all web pages out of embedded viewing in Teams, but shouldn't it then be a very high priority for microsoft to have loop as a teams app?
I really don't know what MS wants us to use Teams for, except for chatting.
