Just was checking to see if the new formats from RFC-93 had made it back in. They have (much appreciated!), but there's an additional three beyond those which were never approved by the style list, and which have active objections to their addition. (Because they describe details of an existing format (vinyl), not new format types.)

7", 10", and 12" shouldn't be in the list of formats.

Ref: http://bugs.musicbrainz.org/ticket/3941 and http://lists.musicbrainz.org/pipermail/musicbrainz-style/2010-March/008745.html - these 3 never got past that stage.
