Dear shopify, don't add a speed measurement feature if you're not going to have an infrastructure to fix the issues.
Your just freaking out store owners, but making it hard for them to fix the issue.
Apps are important for stores, but they're incredibly bad for pagespeed, especially since their is no way for developers to edit the apps loaded through content for header to apply manual tree shaking, every app added to a store has a cumulative effect on pagespeed.
If your not going to add http2, at least give us a way to treeshake apps.
