Thanks!

One concern I have with using 'keys %$defaults' is that the defaults
are no longer applied in a predictable order.

If I have

default_args:
  elements:
    _Input: [ key: some_value ]
    Text: [ key: another_value ]

the value for 'key' for Text elements is equally likely to end up as
'some_value' or 'another_value', and can even change between different
runs.
