Still lost many hours for asking and debugging, if it ever get answered. Companies don't care, business don't care. They care about shipping feature, easy to find developers. Try explaining that to your PM or boss. In the end money talks.

I never advocated bringing either into a professional environment. I simply stated that there is a viable alternative if someone is looking to play in the space.
