Why not just do it unconditionally? There really is no downside. Doing
it conditionally only makes the generated code slower and mode
complex. For absolutely zero gain, as far as I can tell. Does any
architecture actually do anything wrong?

It's actually closer in spirit to the original "open()" model than the
existing code.
