Does this "existing code" do updates only after checking to ensure that the In bit is not set (off)?
I doubt that. Compatibility arguments are certainly not dismissible; some, even many, of them are substantive; but they are too often advanced as a convenient, not at all substantive rationale for doing nothing. However that may be, I have now devoted more time to this issue than it perhaps deserves. Enough!
