"Wenn man nicht mehr weiter weiß, gründet man einen Arbeitskreis." - Ancient German proverb. (Translation: "If you don't know what to do next, you set up a working group")
Well Rust is always about dozens of teams, myriad committees, sub-committees , groups, sub groups, work groups, governance boards, foundations and so on. Although I don’t know they have such huge budget to run fortune 500 or government style bureaucracy. Or is that same people appear at ten different places.
Budget doesn't really have anything to do with it. The vast majority of people on a team or working group aren't paid to work on Rust; they're volunteers.
