Bro... You can literally do nothing if your a core node runner and nothing changes. It takes a user to update. They don't just roll out automatically to everyone running core.

That’s a good solution tell everyone to run an old version and don’t update lol
You are downplaying the situation. Node service providers like umbrel and start 9 will give users some scary warning messages about updating their node.
Why is that not a good solution? I don't understand the issue with running an older version of core?
