Randy Fisher pointed out that it would be convenient if image names that have been referenced in a gallery but have not yet been uploaded became "red upload links" to simplify populating the missing images.
Apparently this used to be the case. But near as I can figure, r14792 (1.7?) explicitly checkes if the image is thumbnailable and if not then does not try to makeKnownLinkObj() the name. At least two people this week have asked in #mediawiki for this feature. Perhaps a config variable or <gallery> parameter could control this?
This behavior was default in version 1.10 of Mediawiki. At least i think so, my version got some extensions and is a bit customized.
This behaviour already exists for ordinary transclusions of deleted images (redlinks). Can we please have the same in galleries?
