I'm not sure I see the benefits of declaring this in the WSGI environ.
If you're already conceding that each consumer of this may be configured
to ignore it, that's duplicated effort. That is, instead of having a
simple configuration item per app:

    throw_errors = True

...I now have to present the deployer with a more-confusing and more
tightly-coupled option:

    ignore_wsgiorg_throw_errors = True

If both the protocol and my app's API are now more complicated, what
have we gained?
