I didn't know about that project, that's really cool! I'd be curious to know whether the person who devised this scheme was aware of structured meaning representations (UCCA, AMR, ...), and if so, why they chose to create a new meaning representation. Maybe the goals of the project and/or the constraints of Wikidata necessitated this.
Anyway, GUM (and its sister corpus EWT) does have a lot of parsed permissively-licensed text, so whoever's in charge should definitely consider using them. (Amir, the maintainer, is also super friendly and would respond to an email.)
