Yes! And I try to write such that the story points at the gaps, the flaws, the lies - so that even if I don't later provide a direct correction, there's at least an implication of what's missing. I think third-person doesn't bring unreliability to mind nearly as quickly as first-person.

The worldbuilding cheat comes out of my contradictory desire for perfect continuity and internal canon compliance, and my inability to ever fully construct Auriel (the city, to say nothing of the rest of the world). Short of retconning (which is out of proportion to the errors I'd want to fix), character unreliability is the best way to save myself from myself.
