Doug,
The assumption you are making when you do this is that emissions will get worse
if you don't do this. Is that true?

Just to be clear, I was speaking of single or a few vias at places where a
signal changes many layers on a PCB, not for crosstalk control. The purpose is
to keep down emissions or increase immunity on a PCB.
