When ACS UI Chat SDKs will be officially released? Does Microsoft have the official commitment to do so, or they were experimental?

ACS UI Library for iOS is still in beta (the last beta was 6 months ago): https://github.com/Azure/communication-ui-library-ios/blob/main/AzureCommunicationUI/sdk/AzureCommunicationUIChat/CHANGELOG.md
ACS UI Library for Android last beta was 2 years ago: https://github.com/Azure/communication-ui-library-android/blob/main/docs/CHANGELOG_UI_CHAT.md

Microsoft does not recommend using them for production:
https://learn.microsoft.com/en-us/azure/communication-services/quickstarts/ui-library/get-started-chat-ui-library

However, it is completely unclear what Microsoft's commitment is to promoting those SDKs to the official releases, nether the time of the official UI SDK releases.

Are those UI SDKs dead, given no activities on the referenced GitHub repositories above?

Review the linked Android and iOS chat UI changelogs, along with the Azure Communication Services chat UI library guidance. Determine whether the issue can be answered with an official release commitment or status update; done means documenting a clear, supported answer about the SDKs' production readiness and release plans.
