Can you cite any sources for these concerns? From what I can tell the hypothesis that potassium intake around the RDA will cause renal damage in the long term doesn't have much evidence to single it out for worry.

Fat-soluble vitamins (like vitamin K, and apparently unlike potassium) have long-term exposure health risks - they aren't effectively regulated in the digestive system, and they build up in the body to potentially dangerous levels.
