Sincere question: how do you leak irreversible schema changes to a subset of accounts? Isn't the point of the leak that you're not confident and might need to reverse it? Or are you willing to let those accounts get hosed?

Fix it by hand. If it's ten accounts, that's pretty easy. If it's ten thousand, more of a problem.

When you read irreversible, think "very difficult to reverse and not worth the cost of writing and validating code we don't ever expect to run."
