As other users have already pointed out, the foreshadowing doesn't work in this case, simply because Sakura is finished in developepent as a character the same way as are her teammates Naruto and Sasuke. If she belonged to any more or less renowned clan, it would've been already revealed, as it happened in case of Naruto and Sasuke. This chapter scan has absolutely no meaning now, since Naruto manga is completed a while ago, and Kishimoto isn't even writing the current Boruto manga himself, but only supervising it. What's more important, no reasons to believe some Haruno revelations can await us there because the manga is focused on the new generation instead of old one. Plus, just to note, Sakura is technically an Uchiha clan member now upon marrying Sasuke, the same way as Sarada is.

P. S. Foreshadowing can't be called a proof, only a clear statement is. Thus, no Haruno clan.
