I guess that all depends on the approach taken. Soil builds up over time and the charcoal buried 10 years ago is now further below the surface. As I pointed out in my post above,
TP shows layers of different microbial activity/species (soil horizons). The pictures I've seen of studies of Amazonian
TP show pits several feet deep with several feet being
TP. That can only happen through tilling several feet deep or, much more likely, a gradual build up over time.
You are correct that it is not like fertilizer and water, but I would question a claim such as "Does not need re-application".
With the sprinkler idea, you could control the amount of charcoal applied and perhaps only do it once a year.
I think it is premature to throw the idea out altogether.
