Specificationhttps://html.spec.whatwg.org/multipage/forms.html#attr-form-rel

Summary

This feature adds the "rel" attribute to form elements, which makes it
possible to prevent window.opener from being present on websites navigated
to by form elements which have rel=noopener and prevent the referer header
from being sent with rel=noreferrer.

Risks


Interoperability and Compatibility

This has low interoperability risk because Safari has already shipped this
feature. There are no negative signals from Firefox.


Gecko: No signal (https://bugzilla.mozilla.org/show_bug.cgi?id=1509346)

WebKit: Shipped/Shipping (https://bugs.webkit.org/show_bug.cgi?id=232243)

Web developers: No signals

Other signals:

Ergonomics

I don't think this feature will be used in tandem with other features.


Activation

I don't think it would be challenging for developers to start using this
right away. I don't think it would be helpful to make a polyfill, build on
top of this, or do significant outreach. This is already documented as
supporting form elements on MDN:
https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/rel


Security

There are no security considerations with this feature.


WebView application risks

Does this intent deprecate or change behavior of existing APIs, such that
it has potentially high risk for Android WebView-based applications?

This does not deprecate any APIs and does not have any particular risk for
WebView.


Debuggability

No DevTools support will be needed.

Anticipated spec changes

Open questions about a feature may be a source of future web compat or
interop issues. Please list open issues (e.g. links to known github issues
in the project for the feature specification) whose resolution may
introduce web compat/interop risk (e.g., changing to naming or structure of
the API in a non-backward-compatible way).
No anticipated spec changes.
