Return value

What information was incorrect, unhelpful, or incomplete?

I think it would be useful to mention that dynamic imports can fail if the user isn't connected to the internet. This is important for mobile users with spotty internet connections. Ideally it would be useful to document what kinds of errors different browsers return when a dynamic import request fails, and if it's possible to disambiguate between the server returning a 404 and the request failing because there's no internet connection.
Consider the use-case of an application that loads features dynamically as the user performs certain actions.

What did you expect to see?

Give an example of what happens if the user isn't connected to the internet when calling import(). Is the failure cached or can the developer just retry the request when the internet is back?

Actually, it would be very useful to document how caching impacts dynamic module imports as well.
