My spindle is grounded, which seems to also ground my bits, so there is nothing to clip on, and I have a block of cast aluminium which I use as a Z touch off puck on a coiled wire which can reach anywhere on the bed. I do my tool changes manually, and it's really no extra trouble to do a new touch off. Sometimes I even change touch off references during a job deliberately. The time saving (if any) of a fixed probe which would take up usable bed space is of zero interest, because I'm there anyway and it literally takes seconds. In three years I've broken a single £4 Vbit through accidentally driving it into my touch off puck (I got a cable stuck around my hand pendant which unexpectedly drove the Z down and made a whoopsie) so it's not a massive safety issue, other times the tool is strong enough and it just stalls the Z axis.

Soo, yeah, don't see the point. If I had ATC that would be a completely different story.
