Please add support for Steam to the social connections API. They expose a simple oAuth 2 endpoint.
This is a great suggestion - we don’t have plans to do it in the short term since we don’t have a dedicated page for “connections”.
Since I can think of legitimate use cases for this, I will definitely consider this.
For what it’s worth, my entire Patreon is a legitimate use-case. I’m currently recommending people put their public Steam Community profile URLs in their about box so I can parse it from there. It’s not ideal, though.
