I follow that idea. However, the game manual puts those functions you describe under the action gauge. The manual states that the charging of energy and triggering of the Chaos Boost is a part of the Action Gauge, meaning that it is the same mechanic, but it just have features exclusively for Shadow. See here It is weird and stupid to include it in the other characters then, but we have to remember that the game was rushed.
