Kodachi didn't have to introduce the Jogan. Even if Kishimoto forgot to introduce Boruto with the Byakugan, Kodachi could have just awakened it in him at about the same time as he introduced the Jogan, with a minimum of inconsistency. But, instead of slipping in the Byakugan (which might have been simpler), he opted to introduce the Jogan.

No, while it may have been late and even a bit improv, I get the impression the Jogan has a distinct origin and purpose, even if we aren't privy to it yet.
