Because we use a tabbed experience to highlight how to configure the feed in a specific repository server, would it not make sense to use a similar tabbed experience for the setup, since we know the shape of the url required by each provider?

Bonus points for a box they can provide what they named the feed so it's a literal copy/paste operation. (Authentication not withstanding)

Adding a source doesn't change depending on the repository solution, so the tabbed interface is overkill.

I considered implementing this, but it also felt like overkill given it's two lines of code a user would need to run. The example provided can be copy/pasted, and the user can then make any changes to that before running the code because as you mentioned they would still need to add authentication and any options they require.
