Note: the extension should probably both output a string value and set an appropriate exit code.

@kylewillmon I didn't find it in the Notion user story, but did you question whether this was necessary at all, or was that someone else?

I'd like to bring this up again since I'm not sure this is necessary for the MVP. Extensions depending on each other is something that I'd argue comes with a lot of risks, so it's probably best to approach it with some caution?

I think it was someone else that brought it up initially. But I agree. This should be probably be removed from MVP.

With no objections, I am closing this issue and considering it removed from MVP
