Introducing "Request sign-off" - an approval flow that requires no set up

I really hope that this does not get released without the ability to switch it off. For those of us that have heavily used Document libraries with workflow, we don't want the users to be confused with an option that is different to the intended use.

I love the features that Microsoft is developing, but the ability to control them is critical. Another example is the 'Send by Email' button on modern pages. In classic team sites, this button now appears on all modern pages, which makes no sense.
