Description Michael Grandjean

Scenario: While using the UMC module for user import, a customer used the wrong CSV file which contained only around 20 new users instead of all 3000. They ignored the output of the dry-run and started the import job. The importer then deleted ~3000 students and created 20 new accounts.

Feature Request: To avoid accidents like the one above, the Importer should be able to warn the user if too many deletions are going to happen. 
E.g. if more than XX percent of all users (or more than an absolute number of XX users) with the same source_uid should be deleted, show an additional warning pop-up.

The threshold should be configurable via UCR.

It would be great if "ucs-school-user-import" could do this, too.
