13872	Optionally allow OAuth signing of all API requests	zerebubuth@…	team	"One frequent complaint when large mapping parties are held behind NAT firewalls is that API requests begin to fail with ""509 Bandwith Limit Exceeded"" messages. This is due to the OSM API rate-limiting on the basis of the user's IP address, which may be shared with many other users.

A method was recently committed and deployed to the API which means that OAuth signed requests will count towards a per-user rate limit rather than a per-IP one. This should mostly solve the problem that users behind NAT firewalls have experienced. While it is not necessary to use OAuth to sign read-only requests, such as map API calls, doing so will cause the user to be judged on their own traffic alone.

iD has added support recently, for full details please see: https://github.com/openstreetmap/iD/pull/3519
