I'm sort of inclined to agree with your premise that ADHD may describe how a patient presents without describing the underlying faulty physiology; but, at the same time—it's all about attention.

It doesn't matter how you get there—mechanisms that can improve executive control and control over the mind's salience network will greatly end up benefiting those who suffer with ADHD. Those who practice mindfulness meditation—ADHD sufferers or not—show strengthened neural circuitry in both executive control and salience networks. Head trauma, environmental factors, genetics or what have you; working to strengthen these networks is a good thing.
