Because those pages are unprofessional and can lead to edit wars (mostly for the romance ones; also this is just an assumption based on another wikis reasoning). A Page for Oliver and Felicity’s relationship would be constantly fought over until they have to permanently lock it, Same for Kara and Lena, and Oliver and Laurel, many others would have more common than usual revert wars, yes it works on some wikis but shipping wars are common in this fandom so it’s easier to just avoid the conflicts and unprofessionality by not having them.
