I think GitHub profile maintenance as a service would be quite a business model for body leasing type of consultancies (that cater a particular industry sector) ... for individuals, it would not be very sustainable. Actually, a lot of work maintained by consultancies is half finished non production shovelware, so they probably already do this themselves.
