Cor, not that old chestnut again. Every time somebody suggests a new command for looking at the entity state, somebody else trots out "you already know it because you're using variables." There are a number of problems with that, elaborated many times before, most of which apply just as much here as when they were elaborated. Taking one example, your speed variable wouldn't be known to an included library function, like, say, a physics simulation. This doesn't present an example where EntitySpeed commands would be useful (after all, Tokamak works fine without them) but this example does show that variables don't automatically mean transparent data.
