In working on a project where we were migrating a Drupal 7 site to Drupal 8, I came across a case where we needed to migrate the data from what was a regular text field in the Drupal 7 site into a link field in the new Drupal 8 site. As it was, the YAML for the migration was treating the destination field as a text field as well:
It started with a frantic email from one of my clients. They had accidentally deleted a taxonomy vocabulary and needed help in fixing their site. As I looked into it, I saw just how much damage this had done. This site used Taxonomy Access Control Lite to let contributing users edit parts of the site, and the vocabulary that they deleted was used with this access control. This meant that the access settings were gone now for a couple thousand nodes.
