@jairmyree Are the changes in the azure-sdk-bom fine? I just added it because the referenced package should not be used anymore, but I can also revert the change if you have concerns.

@Azure/azure-sdk-eng Sorry if this hits a few to many people, but are the changes here in the eng/ directory fine? I just don't know if keeping these references around will eventually break things with the packages not being worked on. Should I reverse the changes or just keep it?

@RamonArguelles As you are the only code owner of azure-mixedreality-authenticator. Could you also approve if you agree with removing the SDK?

@weidongxu-microsoft Is it okay to remove the sdk/azure-resourcemanager-mixedreality and change the sdk/resourcemanager/docs? The resource providers on the Azure Portal side are retired so, if this is for creating resources of these types then they shouldn't have any purpose anymore.

The sdk/azure-resourcemanager-mixedreality lib has not yet to be marked as deprecated. It needs to have a release to mark it as deprecated on package manager. Code can be deleted after the maintenance period.

The deprecation process is cross-language. Please follow https://eng.ms/docs/products/azure-developer-experience/retirement/sdk-deprecation

The removal of the lib from BOM may not be trivial. CC @jairmyree
