Hex dies are for re-threading damaged threads.
Split-dies accomplish proper threads from the solid.
Simply examine the tool in question, and resulting chips. Ask anyone with a background in mass manufacture processes. The only common solid dies are known as "Acorn dies", used in vast numbers of turret lathes and screw machines, especially smaller diameters & pitch combinations.

Shop Practice 101 (not unproved theory, 'looks like', or uninformed short cuts).

Not ALL hex dies are for rethreading/thread repair.

I have a Craftsman die set (bought MANY, MANY years ago) where all the dies are hex as is the wrench which holds them. They work as well as the circular split dies I acquired later. Replacement dies are still available on the Bay...

True enough.

I also have ancient Craftsman hex dies; from a 1970's garage sale.
While they'll thread solid stock, most seem to be high carbon steel, not HSS. So they balk at anything beyond mild steel. Anything beyond 302 stainless, uhhh, no. Lots of good tool companies marketed hex dies (and still do), always felt geared to mechanics - work pieces in close quarters and/ or not easily removed, when a ratchet beats a die stock, hands down.
Newer made, find them and the tap wrenches have wrong ergonomics; slick chrome, indistinct ratcheting CW/ CCW, handles tapered incorrectly, all irritating. Too many 'features', few benefits.

I know a least one "Hear Ye, Hear Ye" inbound about slick chrome, our pal in TX.
