So I uploaded a pic with two married female characters and was going to tag it as wife_and_wife, until I noticed that the wiki page calls for no "outside information" regarding the tag (the same applies to husband_and_husband, I believe). Since there was no explicit info in the pic itself I left the tag off, but then started thinking that the tag would probably be better served as a _(lore) tag.
But then I kept thinking about it: husband_and_wife is, as of writing, at around 7.3k, and that tag is filled with pics where it's not clear upon first look that the couple are married. If you knew nothing about Fantastic Mr. Fox, would you be able to tell that these two are married? Or didn't know anything about Helluva Boss? Or The Amazing World of Gumball?
Because of this heavy reliance on outside info, I'm both asking for public opinion & proposing that the husband_and_wife, husband_and_husband and wife_and_wife tags should be treated like all the other familial relationship tags and be marked as lore tags. So something like:
husband_and_wife_(lore)
husband_and_husband_(lore)
wife_and_wife_(lore)
Or, if the last two read as clunky (and people would be open to aliasing them away):
husband_and_wife_(lore)
husbands_(lore)
wives_(lore)
