I agree with the future of a lock nut system, even the savage style. The AR type looks interesting but the other one with set screws in the action locking up the barrel will be a short lived woodie. It's designed to fail.
Not everyone is Tom who can get his gunsmith to perform miracles. Like overnight barrels, modifications, stock work, etc,etc. Most of us are held ransom for months, years even. I have various actions, all with non compatable tenons. say
I wanted to use a barrel from a bat, I'd have to have another barrel chambered with same reamer and fitted to my other action.
For the non wood dreamers, the most who are social shooters, pd, shooters and just plain fun shooters, Hunters, could have a handful of barrels chambered and threaded to the most common thread pitch and use locking double nuts or the AR style or a similar setup. Then you would have total control of your mix and match, without having to pay twice and wait twice as long for gunsmiths to deliver your barrels.
I say the market it eager for a better way. As soon as the high end target folks tone down the need to spend thousands of dollars for parts and then send them to them to tweak the parts so you will have a .001 agg rifle that you don't need, nor could you shoot it that well, if you had to.
The nut systems should easily shoot under.250, and if you need anymore than that you should be calling guys like ?Alex and pay the piper.
We already determined the quality of threads and action threads were purely aesthetics and machinists pride or ego. The issue about cambering has been debunked, and the only thing that matters is in the neck being concentric to the bore. We have even shown that bolt bodies are better loose.
With all these details not needing to be precise, I'm a bit baffled as to why these same people say such bad things about barrel nuts.
From my take of the need or not... for precision fits on the tenon and action, the barrel nut locking system would all but have to be a plus.
