Not everybody outside the stdlib is using the python unittest module to 
test pure-python code.

I don't think that every single third-party test suite is using every 
single feature of the existing unittest module either, though.

This makes sense to me, and I won't belabor the point.  I just wanted to 
give a gentle reminder that if this functionality is useful to the 
standard library, it's likely that there are other libraries it would be 
useful to.  Not putting it into the supported library right away makes 
sense, but if this functionality does prove useful, please consider 
making it standard.
