Doing some perf testing this weekend to confirm, but we may have come up with the best performing general-purpose bundling strategy in the game right now (and you don't even need to use a bundler 🤣)
1. Each pkg is installed to web_modules/ as a single JS file
2. With HTTP/2, this performs as well as a single bundle (vs. individual files which perform worse, even with H2 enabled)
3. Files only change when updated, letting the browser cache unchanged deps indefinitely
