Specification
https://urlpattern.spec.whatwg.org/#dom-urlpattern-hasregexpgroups

Summary

Allows easy inspection of whether a URLPattern uses one or more ECMAScript
regular expression groups, and therefore may not be suitable for use in
cases where an ECMAScript engine is not available (such as some upcoming
planned APIs). Strictly speaking this reflects back something developers
could know anyway from inspecting the pattern, but having easy access to
the UA's implementation of this check makes that more straightforward.

Risks


Interoperability and Compatibility

Interoperability risk is low. The feature is simple, has a small API
surface area, and is easy to implement. It could be polyfilled if other
browser vendors implemented URLPattern but not this feature, though that
outcome does not seem likely.


*Gecko*: No signal (
https://mozilla.github.io/standards-positions/#urlpattern) This addition is
too trivial to request a separate position, but Mozilla is positive on
URLPattern generally.

*WebKit*: No signal (https://webkit.org/standards-positions/#position-61)
This addition is too trivial to request a separate position, but WebKit is
positive on URLPattern generally.

*Web developers*: No signals No significant signals, but this feature is
trivial

*Other signals*:

Ergonomics

No significant concerns anticipated


Activation

No; in fact this property is added specifically to make activation of
features which can only accept patterns with no regexp groups easier.


Security

No security risks have been identified.


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

Standard developer tools (e.g., the JavaScript console) are likely to be
sufficient. If URL patterns become extremely popular one could imagine
tools particular to them, but those could be developed independently of
this ship decision.


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

Availability expectationDependent on implementation of URL Pattern API in
non-Chromium browsers.

Estimated milestones
Shipping on desktop 122
Shipping on Android 122
Shipping on WebView 122
If approvals arrive in time for 121 branch, I'll enable this in 121, but
I'm currently assuming not.

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).
None
