Could there be a slight change in permissions regarding 'vanish.see' to be changed to 'vanish.see.[Permission grouping]', where '[permission grouping]' is the superperms group that they are able to see vanished members of? My reason for this would be that I'm experimenting with adding a Greylist to my server, and to prevent Greylisted players from being disruptive to those on the Whitelist, as it's an RP server, I've made them invisible with vanish.joinvanished, while withholding vanish.vanish or vanish.off. The issue is that I want them to be able to see each other, so I would give them 'vanish.see', but I would like it if there were a way to prevent them from seeing vanished admins as well.

P.S. I did not no where else to put suggestions, if you take them, so I put this here. If there is somewhere else I should have put it, I will gladly put it there if redirected.

there is no such thing as a superperms group.

I will however be working on a group management feature in 4.0
