Here's look at a Hauser with the adjustable neck angle and inset heel: https://www.luthiersforum.com/forum/viewtopic.php?f=10101&t=47791&p=632106&hilit=hauser#p632106
There have been a number of these innovative neck joints over the years including Taylor guitars today. It's true that Taylor has taken much of the drama and expense out of neck resets but not everyone is a fan of Taylor's tone and offerings.
The guitar world is still very much dominated by traditionalists who value the simple and successful designs of the past such as a D-18, D-28 etc. And as you know these designs will need a neck reset in time.
Our position on neck resets has morphed, evolved, changed and in my case come full circle. I used to value some of the efforts, not all to make neck resets something of the past. But sadly many of the implementations look like someone with a hardware store fetish got drunk and went to town. You will always have the remnants of the argument against Taylor's original sin.... b*lt-on neck design too arguing that nothing sounds as good as a traditional HHG dovetail neck joint.
We are seeing neck resets as part of normal maintenance now and something to simply expect to have to do in time.
It seems that there will always be efforts to innovate but it just may be that most of the time, not always.... these things have been considered prior by some very bright folks and there are good reason why next joints such as the Hauser design aren't standard on today's instruments.
I guess I'm firmly old school now. Go figure.
