About the "character specific" tag

To me, this tag seems redundant, as I would think character specific works would have the character marked as a source tag with little to no other source tags. Having one character marked as a source on a work should implicitly convey the idea that the work focuses on them, assuming there isn't a source request. However, I would like to hear some other opinions on this tag. Maybe there is a use case I haven't considered.

I feel that the character_specific tag is justified since having a tag for each character would just be bloat. Considering that some character-specific videos are made based on obscure niche characters, meaning that those extra tags will have only one or two videos, depending on how many times that creator makes a video on that character. Having the character_specific tag and the media tag from where that character is from would simplify things.
