I think that it should not be disallowed the assignment of resources to
summary tasks.  You can use those tasks to add other resources that are
not specific to the tasks but help them or just overhead.

If a task is just a summary of a group of tasks, nothing should be
attached to it to describe what is going to happen downstream.  Any of
its properties is a reflection of the other tasks.

If you add resources to a summary task, it becomes a task that depends
on the other tasks with start-to-start and end-to-end relationships done
automatically.

Just my 2 cents
