Are you doing it for the sake of being able to use fresh developer for
every print or is it something else? (Such as different tonality? Local
development / tone variation?)

According to Sullivan and Weese in their book, 'The New Platinum Print',
brush development provides a method for getting a longer scale print when
dealing with contrasty negatives. That's why I tried it. I can't say that I
met my goal.
You could possibly use this method to alter local contrast by using
different dilutions of dichromate in the potassium oxalate but it would be a
tricky process to control precisely.
And one of the side effects of using this method is that the developer is
always fresh and contains no build up of platinum or palladium salts, which
is a very good way to test different contrast mixtures of either the
developer or sensitizer.
