By martijnvermaat:

I think in aggressive mode, a missing quality value should be changed to `None`, as I did in my branch: martijnvermaat@aba54d284773f6d05ea1e9c5e50113c5618f70cb

Anyway, I'm not too sure that having two 'modes' is a good thing and would rather see the aggressive behavior be the default.
