What are the benefits of using dynamic supervisor when supervisor also has start_child to start workers dynamically?

I was going through the docs of both supervisor and dynamic supervisor and saw that supervisor also has the function start_child that will allow us to start a worker dynamically using child_spec. Can anyone please elaborate what additional benefits DynamicSupervisor offers us since we can start workers dynamically using Supervisor module as well ?

We can already start a child in the normal Supervisor by passing in a child spec so what benefits does DynamicSupervisor give us?

DynamicSupervisor supports the extra_arguments option, designed to replace the behavior of simple_one_for_one Supervisors.

DynamicSupervisor also supports a max_children option.
