WebGL PWA using AWS Amplify

I’ve made a test build for brotli, and it seemed to work ok. I’ve followed this post for setting up the meta tags/ upload using a batch file or auto lambdas. (We build using guithub mainly though, I use batch files and lambdas for fast iteration) in aws: AWS for WebGL Hosting
In what cases does brotli break? I was considering updating to it.
