This feels like something that has the potential to be rather thorny...
I would expect 0.001% on Beta to be higher on Stable.
Given that your UMA
<https://chromiumdash.appspot.com/commit/155a6cac4aab72685cfcc39029739394243ed1ef>
landed in M120, could we wait a few weeks to look at the stable data,
then come back with an Intent to Ship? This seems slightly riskier for a
page than

(which had server-side validation as a fallback).

Specification
https://urlpattern.spec.whatwg.org
Summary
The URL Pattern API allows developers to specify pattern strings.
Those are transformed to regular expressions internally. When the API
was first implemented, these regular expressions were compiled with
the u flag. We're going to update it to the v flag, enabling Unicode
sets

Interoperability and Compatibility
https://github.com/tc39/proposal-regexp-v-flag#how-is-the-v-flag-different-from-the-u-flag
This doc has a list the potentially breaking changes between u and v.
Some patterns that previously would compile, now throw an error with
the v flag, specifically those with a character class including either
an unescaped special character or a double punctuator. I believe it
does not significantly affect the patterns in use today. From UMA
metric on Beta, incompatible patterns are less than 0.001% of the
total compilation. Also, the use counter of the API itself has only
0.11%. The expected impact is extremely limited.

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).
