Thought: This makes DateTimeFormatter<YMDHMSZ> a little bit bigger in stack size.

Praise: 1'979'623B to 1'435'127B is a big enough improvement that I'm happy landing this despite my other comments.

A lot of location names are the same in many languages.
For exemplar cities we have root data, however for territories we don't. For territories I'm resolving the
undname by using a Latin-script endonym (i.e. for regionXY, resolveund-Latn-XY), and if that fails, just use English (not perfect, but it's better than the raw region code for both display purposes and deduplication).
