Upgrade UI module (similar to Migrate UI in D8) to help with moving from D7

Drupal 8 includes a "Migrate UI" module helps people upgrade from Drupal 7 to Drupal 8. I'd like to see something similar for Backdrop that will help people move from Drupal 7.

The Drupal 8 also provides data on available upgrade paths (similar to what we can provide with https://github.com/backdrop-contrib/backdrop_upgrade_status) as well as an interface for uploading both files and database from an existing Drupal 7 site, into the current Backdrop site.

The first page of the upgrade process contains instructions:

The second page asks for your Drupal 7 database and Drupal 7 files:

The third page does an analysis of the modules you've installed on the new/empty (Backdrop) site and what's in the old legacy database, and generates a report:

If the new new/empty (Backdrop) site has content it it, it throws a warning first:

I would like to start working on this as a contrib module, but am interested to see what other people think about having something like this in core.
