In the same way as existing sites can be "upgraded" to "Connect to new Office 365 Group", it would be great if one could go the other way around as well.

We have some sites that were initially created with Office 365 Group. But over time, we see that the functionality for this is not being used at all.

So it would be great if we could get functionality for "cleaning up" or removing the Office 365 Group for a site, or convert it to a standard Team Site (with no Office 365 Group).
