Mocking is bad at many things, and email is a bad way to express
generalizations through exaggeration. I would almost certainly not
actually mock anyone.
I doubt very seriously that any of us here working on OpenStack lack the
ability to develop.
In response to your question though- I find that when the process of
debugging an error involves editing an installed library to remove an
improperly done exception translation so that I can actually see the
traceback and find the error, then someone has made the wrong choice in
their implementation of the library.
