If you set a taxonomy field in Drupal 7 to use the Rendered Entity field formatter in a display mode, like this:

And then you attempt to migrate that to Drupal 8 with the following commands:
composer require drupal/migrate_tools:4.x-dev drupal/migrate_upgrade:3.x-dev drupal/migrate_plus:4.x-dev
drush en -y migrate_tools,migrate_upgrade,migrate_plus
drush migrate:upgrade --legacy-db-key=drupal7 --legacy-root=/var/www/drupal/drupal7 --configure-only
drush -v migrate:import --execute-dependencies --tag=Configuration
Then the field formatter settings migration fails with the following error:
[error] The "entityreference_entity_view" plugin does not exist. (/var/www/drupal/drupal8/core/lib/Drupal/Component/Plugin/Discovery/DiscoveryTrait.php:52)
[notice] Processed 10 items (9 created, 0 updated, 1 failed, 0 ignored) - done with 'upgrade_d7_field_formatter_settings'
[error] upgrade_d7_field_formatter_settings Migration - 1 failed.
This happens because the Entity Reference module in Drupal 7 adds the Rendered Entity field formatter for both Entity Reference and Taxonomy Reference fields:

However, the Taxonomy Term Reference migrate plugin does not map the formatter:

heddnGreat find. I think this needs tests. We obviously have a scenario that wasn't caught with our existing test coverage.

quietone commented@juampynr, thanks. Thinks for great and is fine by me.
I've decided to add a migration test of the change as well.
