Firefox has about:config as a saving grace, so if options were removed from its user interface, I would be able to make do. In fact, I'd pay money to see about:config or similar in every application. For example, I set slider.snapMultiplier to zero to remove that annoying snap-back on the scrollbar thumb when you drift too far in the perpendicular. Good luck describing that one in a dialog box.
But unfortunately, in other products, hiding options is often just straight-up removing options.
While I appreciate reducing confusion by hiding options that are difficult to describe, I would prefer an "advanced settings" section. Perhaps consider three tiers, as with Firefox (options, advanced, and about:config).
