I’m more concerned about whether the usage of this parameter has been removed from the code. If it has been removed, the impact should not be significant.
I reviewed the code PR, and it has been deleted without any impact, which was surprising. Now, looking at it again, there is a bit of discrepancy between the documentation description and the actual handling. The “deletion” here should be “deprecation.”

As expected, it was just a feint, hahaha
