I don't understand the question.

You can only update from a dictionary (b must be a dictionary or a
ConfigObj).

If *inside* your dictionary a, one of the values is a dictionary (a
subsection) - that can be overwritten if dictionary b has a scalar for
that value.

This should be the same result as for a dictionary.

Can you show me an example (using the new code) that doesn't behave how
you would expect ?

Because all subsections are instances of Section - the new method *is*
recursive (it uses Section.update).
