I'll just add one small comment. If your board vendor says he can remove your
unsupported inner layer pads, with NO COST TO YOU, and make a reliable board
(remember, what does YOUR design requirement say? Is removal acceptable?) for
you, and you're comfortable, HAVE AT IT! Personally, our fab houses have been
stripping the unused pad on inner layers for years (their discretion) AND do
the pad filleting for no cost other than the cost we pay for using "quality"
fab houses.
