Flag Activity

Is there any information anywhere on how the Flag activity is used in practice?

As ever, the spec only tells me that it exists; it doesn't say anything about what it contains, where it gets delivered to, how the recipient processes it, etc.

Maybe I could find out more by setting up some test instances and experimenting with it, or by trying to trawl through various repositories to find the relevant source code - but it seems a lot quicker to just ask.
