Feature or enhancement

Proposal:

>>> ast.dump(ast.arguments())
'arguments(posonlyargs=[], args=[], kwonlyargs=[], kw_defaults=[], defaults=[])'

After #105858, it would be nice if ast.dump() also didn't output optional fields that are set to None or an empty string, so that its output is more concise. This should make it easier to understand the structure of large ASTs where most fields are missing.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
