Azure DevOps Server: Conditions for when provider is required

[Frulfump]

From the README.md
https://github.com/microsoft/artifacts-credprovider?tab=readme-ov-file#azure-devops-server

The Azure Artifacts Credential Provider may not be necessary for an on-premises Azure DevOps Server on Windows

Under which conditions is it required?

Is it only this from the README.md?

From Azure DevOps Server 2020 RC1 forward, the NuGet Authenticate task can be used in Pipelines.

Some packaging clients (like NuGet) automatically pick up default Windows credentials for on-prem feeds, so artifacts-credprovider isn’t needed in those cases. This comment is likely referring to scenarios where clients don’t do this by default. However, even then, I can’t think of a situation where installing artifacts-credprovider, setting feed endpoint URLs with a PAT, and manually rotating that env variable would be simpler than just configuring the client directly with the PAT.

For pipeline scenarios, the NuGetAuthenticate task essentially sets up and configures artifacts-credprovider to run in build mode, so future restores can authenticate without extra steps.
