This hasn't been my experience at all. I regularly check the bitwarden icon for example to make sure I am not on the wrong site (b/c my login count badge is there). In fact autofill has saved me before because it did not recognize the domain and did not fill.

Yeah nor mine. Chrome's password manager / autofill is very reliable and very few sites don't work with it or have multiple domains with the same auth. The only one I can think of is maybe Synopsys Solvnet, but you're probably not using that...
