>do you honestly think anyone would be calling Mahoako yuri if the author was doing artwork of the girls getting fucked by guys?
If it's non-canon, then yes. There are plently of series with no heterosexual elements whatsoever yet have official products where the girls do yuri things with each other. Is GuP a yuri series now because there's official art of Miho/Darjeeling getting married and nothing in the series itself contradicts that.
