It's great that the Migrate Tools commands are included in Drush since Drush 10.4.
As far as I can tell, the only missing command is migrate:tree. I haven't done enough migrations to see how useful it is, but it looks like it could help get a better picture of a migration.
So perhaps it could be considered to also add it to Drush, if it's not too much hassle?
