Those are not even the greatest problem with a single supporter.
Let's take the early days of go: Community asking for a proper dependency management and nothing coming from the authors. Why? 'Cause Google uses a monorepo with everything they need, including external repos. Why would you need dependency management when everything you need is right there.
The community started to get ballistic till
G lang management decided to finally listen to the community and worked on a solution.
So far things are going dandy with management and community, but what if G needs something that's not something the community wants?
Sure, that could happen with more than one supporter too, but it is damn hard to steer things in a direction when you have resistance. So you have to play nice and not screw things for others to move forward.
