I think you have misunderstood what we are discussing, if you are doing a double sided board and a track is required to be connected under the device then you will need a pad. What would you connect the track to? If you have room you could add a via adjacent to the device pad but if not then you need a pad!

Don't put socket pads on the top side of boards. That's a really dumb thing
to do!

If you have a socket on the board you can't get at the top pad to solder it!

What's wrong with simply sticking a wire through the hole and
soldering on
both sides?
