Why are there so few doc stores?

The doc store implementation seems very simple, far simpler than the vector store implementation.

So why are there so few doc stores?

Totally feel this — doc stores are structurally simpler, but they don’t feel "worth it" yet in most stacks.

Vector stores get all the love because they plug directly into RAG flows, eval dashboards, and "AI-ready" semantics.
Doc stores? Still kinda treated like cold storage

What we might need is:

A semantic-native doc store — one that exposes meaning-preserving chunk retrieval, not just basic get/set.
(I’m hacking on something like that myself. Maybe doc stores just need a new goalpost.)

I was actually referring to something slightly different which is that many of the "vector stores" are backends which can store documents but lack doc store implementations
