We have done retroactive MIRs in the past. Also, the security team ACKed the 1.3 version (Focal), the 1.3 version + Ubuntu delta (Jammy) and the upstream 1.4 version (now Kinetic), so we should be fine on that.
I've created the bug tasks for Kinetic/Jammy/Focal, so we can have explicit MIR approval for each series. Let's try to get feedback from the original MIR reviewer about this case.
