Hu was never broken without glitching (bruteforce), the P4 mostly introduced antiglitching. They came out with so many after P4 that there's some believe that either it was broken or they realized the technology could be broken. As far as N3.........there's IKS workarounds already. It could be 2 months or longer before a stand alone release comes out or possibly longer or yeah possibly not in time for people to have moved on.
