I agree a lot with your comment. I do think adding new features is exciting, but if a project is technically interesting (like a kernel is), then there can be great satisfaction in maintaining, as that maintenance can be technically interesting itself. This is not the case if the software is boring from a purely technical standpoint, e.g. some CRUD sales app.
