Just as additional information - Yes, the paper versions are still being accepted but the cut off time for their submittal is different than the electronic cut off time.
The great thing about the new online electronic format is that you can write a proposal, save it...think about it, and come back later and edit it and then submit it. I have (17) submitted so far using that process and all have now been submitted. It's just that easy !
So, by your proposal, I could replace the old panelboard with a gutter, and run ANY distance I want, and then end with a one inch long nipple of sufficient cross section (the raceway) and then be able to invoke the exception to 210.12(B)?
