A couple of years ago (@ a previous company), we did 2 boards w/ HADCO as an
experiment. (Voice and data cards which went in card cage, 12" x 16")
They were existing designs and only left the larger caps on the board (.33uF)
The boards we just as quiet with the plane and no anomilies. (about 2 weeks of
constant test)

Being it was just a test and I left shortly after, I don't know if they went
foward w/ the idea.

I know it saves time in placement and routing.
Frees up routing room.
I would still make provision for added caps @ critical components.
