The amount of accuracy and durability you'd need would be a couple of
aspects to consider.. if one needs to deal with thousands of such fasteners
routinely, they might find it worthwhile to find a good source, such as Apex
or equivalent.

I've had a little difficulty from time to time, in removing a screw from
plastic or sheetmetal consumer products. They aren't too difficult to remove
since they're not torqued very tightly to begin with.
New fastener styles are generally not too difficult to remove.

Left-hand twist drill in a pin vise or suitable handle.
Improvise with a suitable tool.. or modify a low cost more-commonly
available tool.
Slightly damage the appearance of some screwheads, then replace the screws
with standard ones.
Heat the fastener a little.. or more, with a slodering iron tip.
Use one removed screw to use as a die, to then drive a suitably sized
section of mild steel or brass into, or over, to percussively form a custom
tool with, for careful occassional use.

Maybe the manufacturer is just looking for an obvious sign that someone has
done unauthorized modifications to returned equipment.
Sony, for one, will refuse to examine/troubleshoot/estimate repairs, or
accept for exchange.. some of their equipment that has been opened by an end
user.

?Apple is switching to a new type of tamper-resistant screw. This is not a
standard Torx, and there are no readily available screwdrivers that can
remove it. This isn't the first time they've used this type of screw-it
first appeared in the mid-2009 MacBook Pro to prevent you from replacing
the battery-and Apple is using a similar screw on the outer case of the
current MacBook Air.

Gonna make a screw driver.

Small dividing head, ball nosed end mill, and some drill rod.

T&C grinder, indexer, and some drill blank. I think a
triangular shape might work.

Any other ideas?
