I'm not sure how common this is, but our application totally has a middleware to allow simulating other methods via _method and _body querystring parameters in GET requests. I know I've seen many other companies do this. Some may scoff at this for probably naive reasons, but REST doesn't have to mean 'correct' HTTP. It's just an architectural style.
