That's how I see it.  Using historic=qanat for modern qanats seems wrong.
So
if we need different tagging for modern qanats anyway, then handle historic
qanats by adding historic=yes.

See https://wiki.openstreetmap.org/wiki/Historic and then discuss if it
needs
modifying/expanding to specifically deal with qanats or if the page for
man_made=qanat needs text clarifying what Historic means for qanats.

If a historian, even an amateur one, is eager to visit it then it's
historic.
If a historian takes a look and says "Meh" then it isn't historic.  Which
isn't a very objective metric, so some would say the historic tag
shouldn't be used at all (another good reason to prefer man_made=qanat)
over historic=qanat).
