How wild an idea is it to provide *some* compatibility with the plugin 
system for unittest? Are they just too different or could a subset work?

I use unittest because it does 'enough', and none of the extras provided 
by nose or py.test are compelling enough to make me want to jump ship 

Also doing a lot of stuff with IronPython (which neither nose nor 
py.test supports particularly well) it is nice to use the same test 
framework for all my projects.

The fact that they provide stuff I will never use (every large framework 
has that) is not a reason why I don't use them.
