alt Hacker NewsIf I leave a post-it note of passwords on my monitor inside a vault to which only I have access, it’s not a big deal. That’s the point of the “airtight hatch” metaphor.

Right; but in the scenario of this Tweek, you've invited someone untrustworthy into the vault and are then freaking out because they can see the post-it note of passwords. It is inherently irrational.
This issue is inherently unfixable by ANY password manager, because the process model of the underlying OS isn't itself secure. No obfuscation will work, because the password manager itself needs to de-obfuscation it before use (and that memory too is dump-able).
All adding in-memory obfuscation does it make ignorant people feel better, while not moving the security needle even an inch.
I think we've moved away from the secure perimeter thinking and towards defense in depth - if that list of passwords helps you get somewhere other than the vault, removing the post-it improves security. Vaults get infiltrated all the time - and often in partial ways like being able to see into the vault but not reach in.
