Note that the same warnings exist within the DMP Roadmap codebase. Their warning also states application.js (1.73 MiB) link.

The following check was performed after performing rails assets:clobber && rails assets:precompile each time:

// deployment-portage with webpacker
aaron@ubuntu:~/Documents/GitHub/roadmap
$ ls -lh public/packs/js/application-f9a747a97913655770dd.js
-rw-rw-r-- 1 aaron aaron 1.9M Apr  5 15:23 public/packs/js/application-f9a747a97913655770dd.js

// v4.1.1 upgrade with jsbundling-rails
aaron@ubuntu:~/Documents/GitHub/roadmap
$ ls -lh app/assets/builds/application.js
-rw-rw-r-- 1 aaron aaron 1.8M Apr  5 15:25 app/assets/builds/application.js

Although both files far exceed Webpack's recommended size limit, application.js is slightly smaller after the upgrade.
