Too true !

Is there in enough facetting left in the TORX holes to grind down an
Allen key to near enough match to get enough purchase. Preceeded by
heating with a soldering iron a timed number of seconds, gradually
getting more adventurous with the seconds on repeated attempts, after
cooling off periods

Heating for a timed period is the way I would go. Ten to fifteen
seconds would be a good period. Though if thats what their own techs
do I wouldn't worry too much. On the other hand their own techs will
have access to spares should they damage anything.

Drilling out is likely to heat up anyway in a less controllable way.
If you do drill out use a left hand drill bit (if unavailable from an
engineering supplier then regrind a normal one with the other
set/rake) and left hand action drill

Oww ! Trying to regrind a drill that small is going to be a major pain
in the butt... !

No great precision required as long as used in conjuction with a left hand
drive . Its not so much for drilling out
the screw but just biting into the metal enough at some point to grab the
metal and then along with the localised heating produced, the screw
magically undoes itself.
