I ran into a problem related to this when trying to have Butlers for two different cameras in the same notebook. The error was
`RuntimeError: afw Filters were already defined on [insert long list of FilterDefinitions here]`
In sum, I was told "don't do that" as well as "here is one workaround but it's dangerous to go around resetting filters willy-nilly" and "this ticket should address the issue." Thus, I am documenting my problem here instead of opening a new ticket.
