[QUERY] RegionalAuthority support in Azure identity

[leonard520]

Query/Question RegionalAuthority is a feature in https://github.com/AzureAD/microsoft-authentication-library-for-java I find it was once supported in https://github.com/Azure/azure-sdk-for-java/blob/main/sdk/identity/azure-identity/CHANGELOG.md#140-beta1-2021-09-13 but removed later in https://github.com/Azure/azure-sdk-for-java/blob/main/sdk/identity/azure-identity/CHANGELOG.md#140-2021-10-14

Is it due to there once a bug in microsoft-authentication-library-for-java side?

However, recently the bug should be fixed in 1.12.0 and the sdk has also raise the version. Is there any plan to add the feature support back? https://github.com/AzureAD/microsoft-authentication-library-for-java/releases/tag/v1.12.0

Why is this not a Bug or a feature Request? I am wondering if any reason azure identity don't allow to set the regional value?

Anybody can help to take a look? Thanks!

Do we have a plan to add the feature back? Without it, we are not able to use regional ESTS. Thanks.

We don’t have plans to release the APIs we previously added to specify the ESTS-R region. ESTS-R configuration is only allowed in 1st party applications, and 3rd party applications get errors from the ESTS when they add this configuration, which can be difficult to understand as they contain concepts only familiar to 1st party developers. Because of this we decided not to GA these APIs to avoid confusion for external Azure developers.
