Sure I'd say it's important to have in servers, but considering how much marketshare Apple has in the server field, I'd say that a product like this is going to two types of people. A: Business professionals who probably make things in the media production department of any sort, and B: Rich spoiled hipsters. Neither exactly need ecc ram. Sure it would be nice to have but it's also like saying you need an $80,000 car. Apple needs an HEDT option. Rather it's the Intel 9th gen or future gen, or Threadripper, an HEDT option would be perfectly fine for most who use this and not be $6000 at an entry point. And of course, that why it would never happen as well, because today's Apple who sells $1000 monitor stands basically gets a guaranteed $6000 from anyone wanting upgradability.
