Support for discarded_by?

[caseyprovost]

It would be amazing to have support for a discarded_by association on the models. Does it make sense to add this to the project?

PS I would be happy to open a PR that achieved this if the maintainers feel it is a good addition :)

That's a neat feature, but I think it would be best served by a separate gem that worked in conjunction with discard, as we'd like to keep this gem really small and focused.

Absolutely agreed :)
