UPDATE
It is advisable to vote Nay on Referendum 49. It looks like the runtime upgrade lacked a corresponding Polkadot companion change for #10043, as a result some people may see some errors in the logs of Kusama nodes.
For Kusama an additional runtime upgrade will likely be proposed reverting the issue. Until it is resolved we don't want to risk anything happening on mainnet, so only after we will move to a new upgrade.
