ResearchGate offers to add a DOI on any file upload, if it doesn't already have one. I have in the past cited a few PhD-Theses that contain more information than potential papers, or were available before said papers made it out.
So I'm thinking assigning a DOI to a thesis that is published on the university repository can be helpful in making it more citeable.
Are there any downsides to this that I'm forgetting? Or further advantages?
