Risks
Interoperability and Compatibility
This is a Stage 3 TC39 proposal. No known interop risk. No known web
incompatibility risk.
/Gecko/: Positive Firefox uses V8's regexp engine, so it is not
actually an independent implementation here.
/WebKit/: Shipped/Shipping
(https://bugs.webkit.org/show_bug.cgi?id=252553) Stage 3 TC39 proposal.
/Web developers/: No signals
/Other signals/:
Ergonomics
No known ergonomics risks.
Activation
This is unlikely to be polyfillable since it's adding a new kind of
RegExp syntax.
Security
No known security risks.
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?
None
Debuggability
Debuggable like any other JS RegExp.
Will this feature be supported on all six Blink platforms
(Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?
Yes
Is this feature fully tested by web-platform-tests

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).
