I disagree they shouldn't release these sorts of boards, after all there are people who like to explore them, even if it means dealing with lacking software support, and doing so will make useful libraries available more quickly than if .org is to develop them all in house before releasing. That said, they need to make it very obvious what people are actually buying so no one buys a Primo expecting it to just be an Uno with some extras to both avoid customers getting frustrated and thus maintaining an image of making these kinds of technologies more available to anyone.
I think however .org is not entirely to blame either. A lot of times, people buy stuff without really knowing what they are getting, even with the information available in plain writing and there's only so much .org can do to make things obvious.
