Serious development of the vinyl LP pretty well petered
out in the middle-late 1960s. There have been no new
technical developments that were generally accepted
since then.

I think that you'd be surprised at just how incorrect
that assessment is. DMM is one innovation that has been
added since the '60s

DMM fails the test of general acceptance. Plenty of recordings are being
made by traditional metal plating, to this day. Classic Records for example
if you can believe their PR.

Many current releases are DMM mastered and many aren't. Those that are
benefit from it with quieter surfaces. Also records are premium products
these days with some titles costing as much as $60. They all use
super-high-grade virgin vinyl which was generally not used in vinyl's heyday
- especially for non-classical releases. Even where virgin vinyl was used, it
wasn't of the quality used today.

as well as things like digital lathe control,

Again failing the test of general acceptance. Many experienced cutters
prefer to control the lathe manually to this day.

And many don't. There is no "test of general acceptance". And even if there
were, I doubt that you have a poll of all the mastering engineers in the
business today to be able to tell us what the "general acceptance" actually
is. IOW, you are basing these conclusions on your own prejudices.

better sounding acceleration limiters for the cutter stylus,

Ditto.

Ditto to you as well.

better "lacquer" disc materials (less noise)

Questionable benefit.

To who? You? Given your prejudicial attitude toward vinyl, I don't doubt that
everything associated with LPs is of "questionable value" to you.

My measurements show that modern 180 gram pressings are no quieter than well
made LPs from the 60s and 70s.

Your measurements? Where would you find a large enough cross section of
un-played pressings from the 60s and 70's with which to make such a
comparison?

and generally less 'colored' electronics all through the system.

Not really an advancement of the vinyl LP, but an advancement of the general
audio art.

It would still provide a better sounding LP
