Just punting it to tzinfo to make adjustments, ie effectively just doing what normalize() does creates infinite recursion as there is more arithmetic in there, so it's not quite that simple.

This sounds familiar. Its infinite recursion if the tzinfo does its calculations using localized datetimes. If the tzinfo is stripped for the calculations, there is no tzinfo to recurse into. At least this was how I hoped it would work, and it sucks if it doesn't. You could be right that using the UTC representation internally for datetimes with a tzinfo makes the most sense.
