Can you please add details (a proposed commit message) as that might shed light onto why you may think this is needed/useful?
Please also hide IPv4. Way more important to be able to phase it out than hiding IPv6 these days ;-) I know the code doesn't always do it but when we move it we could clean that up.
Those probably should be resolved or removed?
.Dd update before commit
I think the reason WHY a change is done is super useful in a commit message. And thanks for explaining as "testing" was literally the only thing I could think off why this change could be needed. I'll try and see if I can do a more thorough review if noone else beats me to it.
In general I am fine adding the functionality.
