A compelling post. Something it doesn't mention that I immediately wonder about is how you ensure the decision to escalate from "a quick DM" to a "full business case review" (or whatever) isn't unreasonably biased.

If everyone is working with good intent then this doesn't matter. But the real world is full of unconscious 'isms so I suspect there's a risk that underrepresented folks are more likely to trip the extra process flag and thereby get slowed down disproportionately, leading to negative feedback loops.
