This is not really needed. The gl context is totally tied to the window it is created from by virtue of sharing the context with the paint context of that window and that context always has the visual of the window (which we already can get). Also, all user visible contexts are essentially offscreen contexts, so a visual doesn't make sense for them. They only use FBOs which have whatever format that the users sets up.
