I posted on python dev that this would slow exception checking considerably so that is a concern. As for possible bugs, this has been working in the 2 branch for a while now, so I don't think that is the biggest issue. 
As for possible use cases, writing a wrapper around backend, each with its own exceptions and still being able to catch a 'base' exception in your code while still having the ability to catch specific exceptions, without doing awkward stuff like looking at __cause__ (let alone that you have to reraise that in 2 for code that has to run on both branches). Yes, you could patch the exceptions' bases but that is what Abc was created to avoid. 

Sorry for the mistakes and weird phrasing, posting this off my phone.
