No, because although individually each use case above could be described as niche (maybe) - there’s so many different ones, in so many different industries, there’s clearly a general use case. I’ve been a developer with 18 years commercial experience now and I’ve seen graph databases in all size businesses as I’ve travelled the world, from 1-2 person startups to huge online casinos, heck, I’m a single person startup and I have two myself, one with 200,000,000 nodes and there’s no way a traditional database could do what that system is doing (I tried with Postgres, HBase on Hadoop, and Cassandra) Sure they are not as common as traditional DBs, but they are far from niche, that’s why (as you said in your original post) there’s so many products in this space competing - they are actually a thing, they are actually useful, and for some projects, critical.
