Jeff,

Users are going to expect chamfering if there is an option for it.  I
don't see how you are going to avoid adding chamfering to the spokes
unless we decide to do away with chamfering as an option.  I don't think
that's good idea because right angles on board geometry is generally
frowned upon.
