yes, local sealed hierarchies should be allowed if they are inside the same scope, it's infuriating to have to move the hierarchy as members of the class when you want to write a unit test with everything confined in the same method. 
The same also goes for annotations which are not allowed to be local likewise you can not declare them inside a method of a unit test.
