Yes, but to a lesser extent. Passive Barriers are here to stay and you will inevitably see teams that utilize it to buff the Jinchuuriki and Edo Tensei rares.

Just as an example, Mei and Utakata, or Darui and Ameyuri Ringo.

However, just as you get more ninja that work with barrier ninja, there are also going to be ninja that break barriers. Roshi overrides barriers with his mystery, so it's only valid on turn 1, for example. So basically, yes, they will still be significant, and they will always be significant, but definitely less so than now.
