Migrate fuchsia.intl.PropertyProvider change watcher API to a hanging get design and migrate all existing clients.
Instead of having a single fuchsia.intl.PropertyProvider implemented by intl_services, demonstrate best practices for embedding custom PropertyProviders in Session implementations, ideally with multi-user use cases.
Wire up Dart's Platform.localeName (blocked by Dart SDK #37586).
Wire up and verify Chromium's navigator.language and navigator.languages.

Complete support for ephemeral fonts, i.e. loading fonts as ephemeral packages that are temporarily cached. This requires production support for ephemeral packages in Fuchsia.
- Configure a set of ephemeral fonts to cover all common scripts supported by Unicode. (On target devices with lots of storage space, these don't necessarily need to be ephemeral.)
Add support for font subsetting by allowing single typefaces to be split across multiple files, with metadata mapping code point ranges to files. For large fonts, this would improve loading performance.
Make font service multi-threaded to better handle workloads where a single component is displaying text in many fonts at once, or when multiple components are being displayed side by side.
Use ICU4X to implement real language and script ID matching in font service.
Implement support for async local font loading in Flutter.
Implement support for async local font loading in Chromium.
For workstation product, design and implement a font management UI for reviewing and testing out fonts available in a given build.

Implement a FIDL service that provides a listing of time zone IDs and localized display names. This will initially be used in the workstation product's settings UI.

Design and implement APIs for switching keyboard layouts.
