[v7 Beta Feedback] Missing translations - regression from v6's 40+ locales?

[johanrd]

Description

The v7 beta announcement mentions "easier localization" as a feature, but the @firebase-oss/ui-translations package currently only ships with en-US locale.

FirebaseUI v6 included 40+ locales out of the box:

• ar, bg, ca, cs, da, de, el, es, fa, fi, fil, fr, hi, hr, hu, id, it, iw, ja, ko, lt, lv, nl, no, pl, pt-BR, pt-PT, ro, ru, sk, sl, sr, sv, th, tr, uk, vi, zh-CN, zh-TW, and more.

These were in XTB format in the /translations/ directory.

Current state in v7

Looking at packages/translations/src/locales/, only en-us.ts exists. The registerLocale() API is available for custom locales, but the batteries-included translations that made v6 easy to adopt internationally are missing.

Questions

1. Is migrating the existing v6 translations to v7's TypeScript format planned before stable release?
2. If only a beta limitation: Should this be documented as a known limitation of the beta?
