We already do have more than 3 canonical doujutsu though. We have the progenitor of both Sharingan and Rinnegan, the Rinne Sharingan We have Sharingan We have Rinnegan We have Byakugan We have barely explained Tenseigan We have possibly new doujutsu, Boruto's eye

Then we have 'maybe canon' Ketsuryuugan as well.
