Re: Not usually one for pedantry
Presumably the higher surface area to volume ratio will allow the thermite to burn a lot faster than normal lumpy thermite.
Yes, but I think the issue is controllability. Using a lump of thermite to set off the airbag in the steering column of your car would seem to risk igniting the airbag, and potentially depositing a burning lump of thermite on the lap of the driver having burnt it's way through the intervening material. If you can control the laydown to the micron level discussed then i'd imagine that it opens up the safe, controlled use of thermite for things that it hasn't been safely useable for previously.
