This spawned from a discussion on the chat earlier today. There were some differences of opinion as to whether or not this is a good idea.
In When should we use the anime and manga tags?, we decided to get rid of the tags anime and manga, as they were very prone to misuse. It was not at all obvious that these referred to questions which were asking only about the anime version or manga version (respectively). While it hasn't yet been implemented, presumably a similar fate will eventually meet visual-novel, light-novel, and other similar tags.
There is a way to fix this other than getting rid of the tags. As karategeek6 proposed on his answer there (which has not gotten many comments or votes), we could use more explicit tags like manga-specific and anime-specific. These are more self-explanatory, so they are unlikely to be used inappropriately.
So, in principle, we can keep the tags that got deleted, just with minor modifications to make them less ambiguous. However, it's not clear whether or not we actually want to.
Is it a good idea to re-implement the deleted tags in the form anime-specific and manga-specific, or should we keep things the way they are right now and not have tags for these at all?
