So the one thing here I don't like is that they added 1Password product mentions to the main settings screen of this feature. I have disdain for pushing other companies' paid services in one's own product, and also adding absurdly big logos to go with it. Hopefully this is not the beginning of fishing for new revenue streams at the expense of driving a brand and product against a wall.
I have created a uBlock cosmetic filter to remove that panel.
Otherwise, it's a nice feature, albeit none I've been missing, as I have a dedicated domain for exactly the same use case, as well as a catch-all domain for trash mail.
