The factory name `forLanguageTag` is a bit off-putting, it doesn't seem like
the best name for the factory.
Yes, it already exists and does what's required but you might get better uptake
with a more natural name.
Some alternatives:
- `Locale.of("en_US")` - short and conventional
- `Locale.ofLanguage("en_US")` - 'of' prefix is used in other factories
- `Locale.forLanguage("en_US")` - natural but less conventional
