Progress bar for importing

Summary

This issue is a follow up from discussions about the Spinner component.

The goal of this issue is to discuss if a progress bar is suitable for longer running processes. For example running an import or a migration.

Question

Is a progress bar suitable for use to show the progress of an import, or even a batch of imports?

I had assumed not, because of the following

The progress indicator is a static representation of progress at a given point of time and doesn’t animate.
