Even if that were true for this example, the signal-based model grows linearly in complexity and overhead with the number of derived nodes. The callback-based version is super linear in complexity because you have an undefined/ unpredictable evaluation order for callbacks producing a combinatorial explosion of possible side effect traces. It also scales less efficiently because you could potentially run side effects and updates multiple times, where the signal version makes additional guarantees that can prevent this.
