This is currently expected behavior. While not ideal, each locale's data has a minimal size and will feature some additional upcoming size reductions. Additionally it typically compresses well. Also, we are evaluating the use of the standard Intl API as a replacement for these files which would eliminate their inclusion in the application bundles.

Thank you for submitting your feature request! Looks like during the polling process it didn't collect a sufficient number of votes to move to the next stage.

We want to keep Angular rich and ergonomic and at the same time be mindful about its scope and learning journey. If you think your request could live outside Angular's scope, we'd encourage you to collaborate with the community on publishing it as an open source package.
