I went to Google and easily found the following references:

Okay, but you should have easily found that there was not much information at the Vanderbilt link above, except that VANLUBE W-324, their product containing dialkylammonium tungstate, is listed as a 'new product'.
If you search for VANLUBE W-324, here's the
spec sheet. But, there's not much real information here either, particularly as to applications. Four product tests are listed, for one of which one of Vanderbilt's own moly product actually performed slightly better. For all of the tests, it's worth noting that the performance differences between the various products tested was very slight - truly microscopic - if you study the scales on the charts. But, VANLUBE W-324 is an interesting product nonetheless.

MoS2 falling out of suspension is a known issue. Sub-micron particle size seems to be a suitable fix. I've not read of issues involving MoS2 not attaching to metal surfaces.

Where do you get this stuff? It really sounds good, but according to
this Wiki's article on organo-metallic chemistry, there's no particular link between this
very new technology and oil additives. In any event, the bond between MoS2 and metal surfaces should be mechanical - not chemical. MoS2 is not soluble in oil (or much of anything else). But, I'm clearly not a chemist.
As for "extensive lab testing, engine teardown and analysis and fleet testing" we all want that. Who wouldn't want that kind of information? But if that's the standard to be met before using an additive, there would be no additives.
There's a small body of this information on Molybdenum Disulfide used as an oil additive (but clearly not enough to satisfy detractors). And this is a product which has been in rather widespread industrial use for about a century. We can only hope this type of testing is someday done on the organo-metallic flavors of molybdenum and titanium.
