No better reasons Derek!
I always think of queen rearing as a two part process. The first is rearing sealed queen cells and the second getting them mated and in their host colonies. You can concentrate on either or both parts.
I echo Adam’s lukewarm view on some methods which just make a colony queenless and let them raise cells, partly because they waste effort on lots of poorly made cells and you may only use the better ones. You will get serviceable queens as a get out of jail certainly, but it’s not aiming very high.
There is nothing to stop you making dipped beeswax grafting cups or practicing grafting without using the result. You may find a cheap pair of dedicated high magnification glasses or cheap loupe help to see larvae. If you are using a queenright method, clipping your host queen beforehand may reduce the potential for Sods Law to kick in if they try to swarm anyway whilst raising cells.
You could just use the queen cells produced naturally by your better colony by keeping them slightly congested in the spring and feeding gently. Simple. Let’s you concentrate on the mating and introduction part. Not convinced personally about the simplification that cells raised under the swarm impulse begat swarmy bees. The cell has no such intrinsic motivation - it’s the genetics of the queen and drones she mated with and those of the subsequent daughter and her partners. It would obviously be daft to choose to breed from your first to naturally swarm which produced dozens of cells and reswarmed the same season - so you would not do it. You are never going to go from a happy local bee to a Superbee in one generation even if you have fifty hives to choose from so don’t expect miraculous progeny.
A hugely satisfying process which, like most beekeeping, can be made wildly over complicated if you so choose!
