Seems like changing out a broken bit would be a PITA if it's located
under a stage or table. For manual drilling, I just don't see the big
advantage of the "bottom up" method over a standard precision drill
press with an illuminated magnifier attached.

Parallax error. The planar view of the trace on the board
was a big help. The drill was swapped easiy from under
the table.
