I'm -1 for this one.
Changing these would satisfy a linter, but YamllintConfig.extend() can raise something else than an AssertionError (moreover we may change in the future). With except Exception as e, any present or future problem will continue to be caught.

[DimitriPapadopoulos]

Agreed. The idea is that you must know and document the exceptions raised by a piece code. While this might nice be in simple cases and deep in function call trees, it is not always feasible higher in a function call tree, especially when like here you do want to catch any exception.
