The issue with waterway=qanat could be that it is only applicable to those structures that still carry water, while many of them will not be in a working state, or maybe I’m misguided?
I could imagine using historic=aqueduct with a subtag aqueduct=qanat for all of them, and add the waterway tag to distinguish working from nonworking?
I’ve found a short article about these in Bal‘harm, a city in Sicily which is now better known by its current name Palermo: http://www.bestofsicily.com/mag/art154.htm
There’s a map that suggests there are really a lot of these underground tunnels, but the article also states that most aren’t in a working condition:
