But this could be easier. What I hate about Wikimedia's format is templates. They are not very human-editable (try editing a template sometime; unless you're an absolute pro, you will break thousands of articles and be kindly asked to never to do that again) and not very computer-parseable. They're just the first thing someone thought of that worked with MediaWiki's existing feature set and put the right thing on the screen.
Replacing templates with something better -- which would require a project-wide engineering effort -- could make things more accessible to everyone.
FWIW, I do make the intermediate results of my parser downloadable, although to consider them "released" would require documenting them. For example: [1]

The burden of repurposing falls on you and wikipedia makes the exact same data that they have at their disposal available to you, to expect it in a more structured format that is usable by you and your project but that goes beyond what Wikipedia needs in order to function is asking for a bit much I think.
They make the dumps available, they make the parser they use available, what more could you reasonably ask for that does not exceed the intended use case for Wikipedia?
Afaics any work they do that increases the burden on Wikipedia contributors that would make your life easier would be too much.
But since you are already so far along with this and you have your parser, what you could do is to re-release your own intermediary format dumps that would make the lives of other researchers easier.
