Merging into older releases is not a priority for this bug. Fixed in 4.6 and newer. Closing.
Service Delivery has a major need for this, as we can't tolerate the noise but also won't and can't force customers into upgrading
The critical alerts are noisy, but we've had them throughout 4.5.z, so the PR not having landed should not block further 4.5.z.
4.5 will shortly move into CVE only patches, I don't think this is going to get backported to 4.5 at this stage in the lifecycle. Will leave open until we have confirmed that this is correct
Discussed within the team, we are going to close this out now as we don't deem this high enough priority to backport to an N-2 release
