BUR #41269 has been approved by @nonamethanks.
deprecate grimm's_fairy_tales
This tag was created back in 2011, first mentioned in forum #61828, with the purpose of pairing together the fairy tales made popular by the Brothers Grimm and their efforts to collect them all together (which you can tell by the fact that the tag creator also supported a more general fairy tale tag to be made, a tag that'll never be given how we nuked mythology, folklore, etc. because those are way too broad).
However, despite existing for over a decade, this tag failed to gain traction, at least over the individual fairy tales associated with the Brothers Grimm. Now, it has to be pointed out that, in contrast to the recently-made Andersen's Fairy Tales, the Brothers Grimm wrote none of the stories. All of them predate them in some shape or form, and can often be referenced without any mention of Grimm whatsoever. While this tag hangs around the 600s, Little Red is in the 2k+ range... and once you remove Red from their tag, you end up in the sub-200s... and removing Snow White puts you in the sub-40s.
I doubt the tag has many folks searching for it at all, especially as it might confuse folks to use it instead of the given fairy tale's copytag. Of the tales listed, only two are chartag only, Golden Goose (Grimm) and Rumpelstiltskin, and you could probably easily give them both their own copytags no problem (and you also have the Frog Prince, a copy-chartag). So I propose deprecating the tag and piecemeal taking it apart, adding tags where necessary, specifically any missing copytags and chartags.
However, if this BUR fails, we need to have a discussion on what purpose this tag should have. Because otherwise it's just going to hang around with basically no purpose.
