I18n, L10n and A11y tend to be very challenging features, making your wishlist a tall order. Solving that will require a larger developer mindshare. (I'm not sure how much of the existing frameworks can be reused here).

Here's the good news! Iced is already a platform native UI toolkit. It powers the Cosmic desktop and a few important applications are based on it. Iced is sure to receive a lot of attention once Cosmic stabilizes. Hopefully, you will get your wish sooner than later.
