Condition gating may fail on canaries
Medium Severity
supportsTurbopackRuleCondition gates on parseSemver(version).major >= 16, which may return undefined for common Next.js version formats like canary/prerelease strings, causing the condition field to be omitted even when Turbopack supports it.

Just came across https://nextjs.org/docs/app/api-reference/config/next-config-js/turbopack#advanced-webpack-loader-conditions when researching for another issue.
We can match the turbopack loaders more strictly to only run on user code. Potentially reduces build times.
Closes #19504 (added automatically)
