Benefits

• Support for canvas

  • Can we treeshake it out if canvas is not opt'ed in
• Support for cross origin iframes
  • https://github.com/getsentry/sentry-javascript/issues/7279
• Less maintenance overhead with our own patched v1
• Fixes
  • https://github.com/getsentry/rrweb/issues/57
  • https://github.com/getsentry/sentry-javascript/issues/8469
  • https://github.com/getsentry/sentry-javascript/issues/8123

Risks:

• Package size is ~40% larger
