I disagree pretty strongly. There's always a judgement call involved, and it's possible for some cases to be exceptional, but as a general guideline we shouldn't be adding prefs to about:config "for power users", because the long-term costs to adding them has shown to be quite significant even in seemingly trivial cases. As Benjamin notes, an add-on is a much better way to suggest people customize these things, and writing an add-on that sets a pref is trivial.
