This sounds like a good way to configure a tool table if you have
holders, but is not useful for changing tools (a different depth 
every time you insert them) during a program run.

True enough.  This wouldn't be useful for a machine using tools like
that.  With end mills and drill bits, though, it would be fine.  On
my small machine I don't think I've ever cut with anything but end
mills, engraving cutters, and drill bits.  They can all be measured
at the same point.
