spring - What's the difference between 'com.microsoft.azure' and 'com.azure'?

Question

When creating a new Spring Boot project using Spring Initializr and adding Azure Support, it adds a dependency to com.microsoft.azure:azure-spring-boot-starter.

implementation 'com.microsoft.azure:azure-spring-boot-starter'

The spring cloud documentation says:

The Azure Support entry contains auto-configuration support for Azure managed services [...]

Now I'd like to send and receive messages from Azure Service Bus and the documentation wants me to add a dependency to azure-servicebus.

implementation 'com.microsoft.azure:azure-spring-boot-starter'
implementation 'com.microsoft.azure:azure-servicebus'

Okay fine. When I now switch over to Microsoft and read the documentation about Service Bus there, it mentions two libraries, where Microsoft states the second one is dated and legacy.

1. azure-messaging-servicebus (latest) implementation 'com.azure:azure-messaging-servicebus:7.0.0'
2. azure-servicebus (legacy) 'com.microsoft.azure:azure-servicebus'

Question

1. Is the Spring Boot documentation just outdated?
2. I have read somewhere that libraries in com.microsoft.com are for managing the resource itself, while libraries in com.azure are for managing the data. Is this true?
3. What is meant by auto-configuration support?

As you can see I am very confused which dependencies I need to add. Also I don't get the difference between packages from com.azure and com.microsoft.azure.

Can someone please shed some light on this?
