LGTM

The only comment I have about this is that if we implement this in the frontend we should decorate it with a big fat warning that is a very destructive action.

Not knowing that much of this integration and WS, but seems good !

Normally we want an approved frontend PR before merging the backend websocket command. I don't see any linked frontend PR.

you're right, there wasn't, got a little too eager to merge! Will get a frontend PR up soon
