a left handed drillbit is significantly better than a conventional one,
since it will be tending towards loosening, not tightening.

yes.  But it is applied to only a few varieties
Removing a broken easy-out is a lot more fun.
There are special fluted tools for trying to remove broken taps, but not
for easy-outs.
Snap-on makes a good quality broken bolt extractor that is specifically
designed so that WHEN it breaks, it leaves enough sticking out to grab
with 5WR Vise-grips.

I have used a type of easy-out with straight flutes (instead of left-hand
thread), that can be used for left handed broken bolts.

I can't recall DELIBERATE shear-head bolts in computers, but I have
removed broken bolts, and even a broken easy-out, from Hitype I printers.
