Thank you community members; this has been resolved now :D
If a mod could mark this as status-closed that would be great thanks!
So, I was doing some editing the other day and I've come to form the opinion that history-of and origins really should become synonyms. This was previously discussed here, but I don't think anything came from it. So I'm renewing the push.
Why should these be synonyms? Well, first take a look at the answer to the aforementioned question.
Also take a look at the usage guides for the two tags:
Use this tag for questions about the history of the genre: the origin and evolution of ideas in speculative fiction.
a tag for questions that seek to identify the first appearances of specific things in the world of scifi and fantasy, like characters, items, themes, and/or theories.
So, I would propose that history-of should become a synonym of origins
