[...] Another expert is more bearish, noting that though a Chinese RCT does show positive results, and the current evidence is convincing, still more studies are needed, with the magnitude of benefit not as large as you would think. That said, because it’s a substitution of sodium for potassium, there’s a double benefit for cardiovascular health; people don’t consume enough potassium, and potassium lowers blood pressure. And while there is a concern that increasing potassium intake across the population can create risk to people with chronic kidney disease, the evidence is that such people tend to suffer from cardiovascular disease anyway – most hypertension sufferers have higher risk of diabetes/obesity etc.

Of huge interest too is potassium substitution; though evidence of that is fairly
new, they think it is a game changer that can accelerate action. They are trying
to figure out the name (e.g. potassium-enriched salts) from a public relations
perspective. Increasing potassium reduces heart disease – it is an effective
strategy. Low sodium salts in general do cost more – perhaps double the price.
Then again, Himalayan salts are similarly twice as expensive, yet people still
buy it – the challenge is getting the message out there, and that it is good for
you (i.e. benefits of potassium); in Australia they are trying to understand the
barriers to scaling up. There is research on how to get potash in a scalable way
– there is a lot of potassium out there, and only a small amount is food grade
(20%), with the rest (80%) used for things like fertilizer.

I am happy to learn that people are working on this :)
And it does make sense that the increased price also creates difficulties for adoption. This certainly isn’t a trivial problem.
Also, I agree that the public relations perspective is important. Here in Germany, there were large health problems due to missing Iodine, which were reduced by fortifying table salt—but even though the necessity for Iodine hasn’t changed, people/products are starting to use the fortified salt less.
