Steps to Reproduce

1. Build an app with 5.33
2. Use source-map-explorer to inspect the dependency
3. Repeat for 6.3.0
4. We observe an increase in the dependency and potential one named for Web

Expected Result

No dependencies on @sentry-internal/browser-utils

Actual Result

Increase in possible unnecessary dependencies

In react-native/sentry 5.33.0, we had the following dependencies pulled after integrating Sentry

    '@sentry',
    '@sentry-internal/tracing',
    '@sentry-internal/feedback/cjs',
    '@sentry-internal/replay-canvas/cjs',

Now, in 6.3.0, it has increased too:

    '@sentry',
    '@sentry-internal/browser-utils/build/cjs',
    '@sentry-internal/browser-utils/build/cjs/instrument',
    '@sentry-internal/browser-utils/build/cjs/metrics',
    '@sentry-internal/browser-utils/build/cjs/metrics/web-vitals',
    '@sentry-internal/browser-utils/build/cjs/metrics/web-vitals/lib',
    '@sentry-internal/browser-utils/build/cjs/metrics/web-vitals/lib/polyfills',
    '@sentry-internal/feedback/build/npm/cjs',
    '@sentry-internal/replay-canvas/build/npm/cjs',
    '@sentry-internal/replay/build/npm/cjs',

We are monitoring our dependencies, more importantly, on boot (which includes Sentry), as we have a critical business flow that requires answering incoming calls within a few milliseconds to seconds. Therefore, having unnecessary dependencies removed is quite essential.

Here, I suspect that browser-utils might be undesired since we are a react-native application and not a web one. Can someone explain why it is there and if it can be removed, if not already done? Thanks

Thank you for reporting @dprevost-LMI 🙇
We will investigate this and iterate back.

Not sure if it's exactly related, but I'm also seeing @sentry-internal/replay/build/npm/esm/index.js in my Expo bundle, despite not using this feature and having no intention of using it.
