The compromise where people use the shoujo-ai tag as a tag that means 'possible romantic relationship during love triangle wooing attempts that isn't obvious if it will turn into Yuri because the romance is one-sided' instead of its actual Mangadex meaning of 'strong friendships between girls with optionally some romantic subtext' isn't great.
I wish this site had Theme (not genre) tags for 'BL', 'GL', and 'Het'. That would solve love triangle stuff because you could mark this manga as both Het and GL. This is how Dynasty solves the problem, and it works very well.
I guess the main problem is that you'd have to mark like 70% of the site as 'Het', and it is usually redundant. Maybe 'Bisexual' as a theme works better then.
Though, I guess my proposed solution doesn't solve the 'one-sided sexual/romantic love' issue either. Dynasty solves that issue via the tag 'Yuri crush'.
