Heh. Everyone says that.
Lay your guitar down flat so you can see underneath the strings.
Then fret it, try really hard to touch the fingerboard down there. Unless you have reeeeaaally flabby fingers, it's not gonna happen.
Scalloping makes sense where the frets are larger since the string has more room to flex/bend down. There you can suffer from fingerboard drag.
But if I were to scallop a neck I'd probably only do 1st-12th or something. Maybe 15th. I've got pretty big hands/fingers and I don't even think the fleshy tips of mine wrap over the string above the 12th on my UV.
