When trying to resurrect #2625696-66: Make migrations themselves plugins instead of config entities → in contrib like
id: migration_config_deriver
deriver: Drupal\migrate_plus\Plugin\MigrationConfigDeriver
this then return $source_plugin_manager->hasDefinition($definition['source']['plugin']); in NoSourcePluginDecorator first throws a notice because source is not defined in the config migration at all and then it gets filtered out because there is no source plugin with an empty id.
Allow through sourceless migrations.
Add a test.
Needs work
11.0 🔥

The change is currently missing an automated test that fails when run with the original code, and succeeds when the bug has been fixed.
