[Speed 0 Defense Tokens Alternative Effects]

The RRG says "If the Defender's Speed is 0, it cannot spend Defense Tokens". Is this only for defensive purposes such as their standard effect or Thermal Shields, or does it also apply to alternate effects such as Turbolaser Reroute Circuits or Commander Vader? For example, may an Onager with the Rakehell title at speed 0 spend its Salvo token during an attack to reroll attack dice using Commander Vader's ability?

[Comms net timing]
