Here no build system / bundler, because this is a lib is that so usefull (KISS) ? (however depthkit version with vite is here : https://github.com/remmel/Depthkit.js/tree/vite)
the only advantages could be :
generate UMD files for people who don't want to use a bundler neither es6 (even old browser handle it with es-module-shims); but old script way - dephkit.umd.cjs
merging in one file (1 http request) for people who are using es6 in browser (without build system) - dephkit.js
having hot reload system for developers who are improving dephtkit
