How about role="textbox"?

Context:
As other people have reported before me, I've got a case in which my input element is a custom web component (let's call it ui-input). There's a native input element inside its shadow DOM, but the top-level element is custom and it seems like there's no way to make the 1Password extension see it and populate it.

Proposition: <ui-input role="textbox" />
Once an element with this exact role is detected [role="textbox"], it would be treated the same as input[type="text"] or input[type="password"]. What I mean by "treated the same as" is - by default, "scan" for the same attributes as you would for a native input - name, placeholder, type="password" etc. In my specific case this would suffice, as my component interface is identical to the native one. But for cases where these attributes are possibly named differently, maybe support to use ARIA attributes.

Reasoning:
1. Very easy to implement
2. It's a natively available attribute
3. It's also a very deliberate way to communicate to any password manager
