I think you might be on to something, in thinking about it in terms of the platform from the perspective of the end user, and what they build on it.

I humbly posit that you might be better off, at least from a communications/marketing perspective, ditching the "vector search without vectors" verbage because that alienates the segment that, uh, for lack of a better term, loves and understands high dimensional applied math, and computers. :)

Perhaps instead find language that couches it as an entirely new category. Blue ocean. Ditch the word "vector" entirely.
