remove implication magazine_cover -> cover
create implication magazine_cover -> cover_page
After topic #30345, evazion found himself attempting to sort through all the cover tags. To quote him from the Discord:
"I got sucked into trying to garden all the cover page related wikis, but they need a lot of work
I'm trying to clarify the difference between cover, cover page, cover image, and back cover
cover is for any type of cover, cover page is for printed media (doujins, comics, magazines, novels), and cover image is for textless cover pages
but it's unclear whether cover page is just for front covers or includes back covers
magazine cover is a weird exception where they're not considered cover pages because of fake magazine covers
so we have cover page = doujin cover, manga cover, comic cover, novel cover but not magazine cover"
A few of us in the server were confused, particularly me and Provence, over the claim made about magazine cover, because fake cover already implies cover and has since 2017 said it counted for cover page. It took me going back to the Oldbooru discussions over the tags for me to find out what was really going on: forum #12098 indicates how the individual cover tags count for both real and fake covers, but still maintains a distinction between magazine cover and cover page, which implies one thing:
The main reason why magazine cover is seperate from cover page is because, at the time, the overwhelming majority of print media covers on Danbooru were magazine covers, so implying it to cover page would've made it harder to find manga, novel, etc. covers.
Now, no matter how true that might've been back then, it's certainly not the case now. While magazine cover still has triple over manga cover and novel cover respectively, the implication of doujin cover to cover page made back in forum #68392 makes this point null and avoid in my eyes: that fucking tag has 35k posts and is liable to being aliased into manga cover or broken up between manga, magazine, novel, etc. for consistency purposes with doujinshi (object) and doujinshi, which would certainly make the majority of the tag not magazine covers. One could even debate the alias of book cover into cover page from topic #5410 because this means that hardback/hardcover books, which I think are otherwise tagged as cover, get tagged the same as paperback/softcover books (though whether that distinction matters to Danbooru is worth discussing).
Regardless, we should deal with this, and finally have magazine cover imply cover page.
