Here is how your PR affects size of JS and CSS bundles shipped to the user's browser:

Sections (~259 bytes added 📈 [gzipped])

name           parsed_size           gzip_size
jetpack-cloud       +793 B  (+0.3%)     +259 B  (+0.3%)

Sections contain code specific for a given set of routes. Is downloaded and parsed only when a particular route is navigated to.

Async-loaded Components (~6 bytes added 📈 [gzipped])

name                                                 parsed_size           gzip_size
async-load-landing-jetpack-cloud-components-sidebar        +26 B  (+0.2%)       +6 B  (+0.1%)

React components that are loaded lazily, when a certain part of UI is displayed for the first time.

What is parsed and gzip size?

Parsed Size: Uncompressed size of the JS and CSS files. This much code needs to be parsed and stored in memory.
Gzip Size: Compressed size of the JS and CSS files. This much data needs to be downloaded over network.
