My understanding is that the concept of Locale is supposed to be a nice way to gather up a bunch of preferences (currency symbol & format, number formatting, favourite breakfast item, etc) which seems like a good way to simplify the preferences setting dance.

The fact that one part - the language translation files - isn’t supported completely doesn’t seem like it should stop us using the rest. Just handle being unable to load them!

We now have a different mechanism for that, which continuously tracks the system???s time zone across daylight savings and location changes. This can be disabled by ???DateAndTime automaticTimezone: false???.

This is to support users who may have been setting their locale manually, or used that preference to enable timezone updating, and are not aware of the new preference. The useLocale preference would govern both the automatic time zone setting in DateAndTime and the use of Locale plugin for language setting at startup.

The general definition of Locale used in software is the Posix standard which doesn’t include the timezone (which I must admit puzzles me a little, but what do I know?)
So my suggestion is to have an auto-tz option and ability to set a specific TZ for whatever reason, and to make locales work even when the translation file(s) may be missing.
