When would I use one over the other? Seems like they do the same thing. Is one deprecated now that components are available?
A component is far more powerful as you can define settings and so make variation to make it reusable in different scenario.
Multi-page section was mainly built to handle navigation in your app. It’s now doable with a component too.
I’m not sure but maybe one remaining advantage for the multi-page section is it will not be rerender when navigating between page if both use the section. I don’t remember if its the case with components. I’m asking the product team to clarify if there is still a point for multi-page section over components, it’s a great question.
Edit : Yes, a multi-page section is still the only way to have part of your UI persisting during navigation (a linked section will not be rerender, and so it will not blink for example)
