"All owners of an application can freely invite new or remove existing developers/owners/readers. I would like the ability to remove myself from an application in which I no longer have any interest, but where my role is currently developer or reader, not owner. I don't think there are any security issues with that ability, and it is annoying to have to contact the current owners to request removal. This is especially relevant when acting as a consultant with a time-limited interest in a project."
