Out of curiosity, can an SNS’s root, governance, index, swap, or ledger canister ids ever change, or are they meant to be fixed for eternity?
I’m not referring about dapp canister ids, which can be removed and re-added later. Just core canisters.
For example, could an SNS put up a vote to replace (remove and then add) the canister id of it’s ledger with another ledger (different canister id)?
