Technically Russia call all it's thermobaric weapons "flamethrowers".
In the sense they do the same thing flamethrowers did (but better. For starters they're rocket launched).
Flamethrowers never killed anyone by setting them on fire, they killed by burning the oxygen in the air (causing immediate asphyxiation/searing of lungs) and creating quick waves of overpressure (nature hates emptiness, if you quickly deplete oxygen, nearest oxygen try to replace the missing one = wind. Really fast wind = overpressure).
The incendiary nature, while powerful psychologically, is a side effect of the physical phenomena that make the flamethrower such a powerful weapon against enclosed positions.
Anyone close enough to a flamethrower flame is dead long before his gear/flesh catches fire.
That's the big problem with the "incendiary weapon treaty" thing.
The USAF was fucking trigger happy with napalm (go ask North Korea. Vietnam got tiny doses of napalm compared to NK), but the thing with napalm (I'm not even sure they actually put napalm in flamethrowers) the infantry used never was primarily used to actually set shit on fire.

>The pressure involved should be enough to send shrapnel at ridiculous speeds for at least a few hundred meters.
Not really. Mainly because thermobaric weapons have an already stupid kill radius, it's dubious adding shrapnel would do anything to increase it while you would add weight. IF you can add weight just put more thermobaric compound.
