Haven't seen many 24V control transformers that will hold off 100kV.

The risk (not huge, but something to think about) is the following sequence:

HV from secondary flashes over, creating moderately low impedance 
connection between 110V side of transformer to 24V side of 
transformer (or, worse, between TC primary with 10kV on it, to 24V 
side of transformer)

Current flows from 110V (or 15kV) through you.

You lie there twitching and/or smoldering, unable to let go, as the 
arc burns happily, roasting you.

A bit extreme, I grant you, but there's a lot to be said for being 
able to disconnect without having to get near ANY wires connected to 
the system.  Or, more to the point, so that someone else, who's 
freaking out at seeing you thrashing about yelling "turn it off! For 
the love of mike, turn it off!" will be able to render the system 
safe.  Nothing discourages a would be helpful bystander like getting 
shocked by the power switch.

Naturally, if your partner is a cool, calm, collected coiler that's a 
member of this list, they'll casually walk over and turn off the 
switch with the insulated "hot stick" they always carry (never know 
when you might need it!), while berating you for damaging the finish 
on your new coil, then calmly restart your heart, and then, of 
course, log in to tell us all about it.
