Why not deprecate it for 3.2 (easy since it's probably not yet used anywhere anyway, even in 2.7) and introduce sys.sysconfig. We already had a lot of churn around these APIs (distutils & friends). I don't think it's a good idea to introduce even more churn. Oh and by the way it's too late to add or remove features from 3.2. I really like that much better than Java-like accessor functions. Do you actually use sysconfig yourself? It's quite a specialized module, and I don't think API elegance arguments have a great weight here.

I have used them and I do think they're fairly ugly and unwieldy. However, I agree that we should not rush into a different design. Since sysconfig was essentially refactored out of distutils (and now we have two ways to do it!), and we're getting distutils2 for 3.3, I think it would be better to work out a more natural design for sysconfig for 3.3. Then the sysconfig module can go through the natural deprecation cycle.
