Example use for RemoveFromContext property?

I'm playing with all the ways data can be constrained/limited (Constrained By, Apply Context, XPath) and come across the opposite: Remove From Context. Can anyone give me a real-world example where this would be useful (see the docs on Content Mechanism at https://world.mendix.com/pages/releaseview.action?pageId=9208573) and where this cannot be done any other way? It looks pretty 'pre-2.5' to me and AFAIK it could be deprecated.

It is a deprecated property indeed, as the errorlist should suggest if you have warnings on.
