I think the subtle question here is exactly what behaviour we want on upgrade. Currently the policy with endport will put endpoints into default deny and therefore lock down the endpoints. If we reject the policy completely, that could mean the policy is ineffective and opens up the endpoints completely if that's the only policy. It may be safer to accept but log, given this is long-standing behaviour (?) |

There was a problem hiding this comment.
I think this makes sense, it's hard for me to argue for something better for the short term and the existing stable releases. I know the support for this feature is making some progress soon so hopefully we won't need a better solution to communicating this problem in the end. 👍
