Review Comment:
@pzampino There are some downsides in moving the logic over to the
`SanitizationException` class. It makes the code less flexible and potentially
harder to maintain (e.g. what if other classes want to throw a
`SanitizedException` but with different logic?). It's also a bit of an effort
to refactor the tests. We haven't decided yet that this pattern is better than
keeping the original `Exception` type (see my previous comment). Finally, but
less important IMO, moving the logic over to `SanitizedException` can be seen
as a violation of the Single Responsibility Principle.
