While true, unless it gains enough speed it might still not properly close by itself. And the door can also be blocked. An angled door will also be a bit heavier to open and more annoying to use. It's not a perfect solution, even if it is helpful.
Maybe an always tensioned hydraulic like on a screen door? I realize this is just self closing and not close on demand, but seems like it would get the job done.
