roslyn: Why do all formatting errors have code IDE0055?

The .editorconfig formatting rules allow quite a varied (and increasing) number of configuration options as to exactly how code should be formatted. It seems quite likely that one would want to have different warning levels for the various different formatting issues, and sometimes want to outright suppress some by setting their severity to ‘none’. However this can’t be done as long as they all throw up the code IDE0055. Why not have different error codes for the different formatting issues to allow more fine-grained control?
