manage a node's local mana list

Iam going to suggest to add interface for GoShimmer to manage nodes’ mana local list.:

  1. list local copy of all nodes with mana, i call it as local mana list.
  2. A node can disable any nodes on the list for FPC opinion, thats mean excluding some nodes as my FPC source.

This can be a helpful mechanism to stop adversary/malicious node’s attacking the tangle.

Further more, a node can manually(by clicking something) import other trusted node’s local mana list, for example under any attacking, my node can copy IF nodes’ local mana list.
( Idea is triggered by Hans’ medium post “The Trust Machine”)

By doing that some nodes/validators governance can be introduced.
