Furthermore, there is the use case to use dgraph locally in a standalone application. It is fast, its supported on windows as a single .exe and really easy to setup with the schema.
I think, it should not be on low priority because it has great potential on windows. Moreover, there was no disclaimer on the downloads page and some (i.e. me) have built a application using dgraph.
Also, its not useable for learning purposes if you need > 8GB of RAM to post one schema.
