right now it is (turned off by default).

If we can get it to the point where it's reasonable to be "On" all the time, it will be a big improvement (builds will be more reproducible, unintended dependencies won't appear, people with crap in /usr/local won't have builds fail for seemingly strange reasons).

If you try it out and find actual problems / have patches to make it better, I'm sure your input would be appreciated :)
