Regarding the "videogallery" tag (and bearing in mind that I don't know if it actually behaves identically to the "gallery" tag in terms of use, features, configuration, et al, having never used or even looked at it myself): simply make it an alias to the "gallery" tag and start undocumenting it on w:c:help: and wherever else. Tag still works as before, use of the tag is discouraged and (in theory) decreases over time, and it gets identical support to "gallery" indefinitely and without any additional developer requirements. Win for everyone!
