isnt the stratocaster rather more heavily chamfered* making a chambered version technically quite difficult to make ?
A tele can easily be made semi-hollow by building the body from two pieces: the main part of the body and then a cap. That’s because the sides are mostly squared off. The contoured edges of the strat body make that a lot harder.
*chamfered refers to the removal of some wood, mainly on the outside cormer where the right arm swings, and also on the back, making it a more snug fit against the chest, or for some, to leave room for an overlarge belly.
