Request for API feature to allow users to change shared link permissions from edit to view only after editing

Being able to edit via api would of course be great, but I can already change permissions for all api generated content to have permissions to edit/comment, so if I changed that permission, my users get the link we provide via api, and then edit those gammas. The only negative is then after they are done, and then they want to share the link with their clients, those clients have the same permission to edit. It would be great if once they edited, they could have the ability to change the permissions to view only. It would make sense if that was something I could allow them to do from the main account page that host the api's.....'allow link recipient to change permissions (from edit/comment to view only)' It would also drive a lot of people into the gamma experience to edit since they have to set up at least a free acct....so there's a benefit, too
