So not necessarily any website, because that could cause issues if one of the prerendered pages runs side-effectful JavaScript.

Then it’s a badly designed website, GET requests (and arguably the JS delivered with a GET-requested HTMl page) should be side-effect free. Side effects should come from explicit user interaction.
