> it'll ding you for loading external files

The Opportunities and Diagnostics sections don't contribute to your Performance score. Your overall Performance score is a weighted average of the Performance metrics [1]. The Opportunities and Diagnostics sections are just potential ideas on changes that may help you. It's up to you to decide what's best for your site.

The Opportunities and Diagnostics sections may not, but your Performance score is affected by loading additional external files.

I've learned a ton for web perf stuff from the devtools and Lighthouse docs, so thanks for your work on those. :)
