The primary purpose is to upload immediately captured content. Why not use the FileAPI directly otherwise?

That said, we should not make changes which lose the primary purpose though we could clarify that file upload is also possible

The advantage over getUserMedia is the purported relative simplicity of using a form to select a device capture without understanding deeper media capture possibilities or having to manage them.
