As I mentioned earlier, I am not against the change as it doesn't have
any other side-effects and just accidentally fixes the issue you have.
But it does sound like a hacky solution to your problem. What if some
other legit reason(theoretically) it needs to be reversed again in the
future. So I am still interested to see if we can fix it without this.
