#1690 was what triggered us to add bundlesize.

Now it's not adding much value. it blocks PRs and we don't see the incremental changes. Also it pings an endpoint on every CI run that 500s and spams our test log. :( We need something better.

A few solutions (some mentioned in #10272):

• https://github.com/siddharthkp/bundlesize - what we got now, nope. @XhmikosR also points out it has native bindings due to brotli. :/
• https://bundlewatch.io/ - basically a bundlesize clone that's good. nah.
• https://github.com/ampproject/filesize - @XhmikosR sez it doesnt seem to integrate with PRs.
• https://github.com/GoogleChromeLabs/travis-size-report - differences against baseline, but only logs in CI, no gh status
• https://buildtracker.dev/ - gotta run your own server but seems nice
• https://github.com/preactjs/compressed-size-action - reports % change against baseline. reports as comment.

I'm very attracted to buildtracker as it charts things over time and not just reporting on this specific one.
