Support package.json subpath exports?

https://nodejs.org/api/packages.html#subpath-exports

Example:

    "exports": {
        ".": "./dist/pocketbase.es.mjs",
        "./cjs": "./dist/pocketbase.cjs.js",
        "./umd": "./dist/pocketbase.umd.js"
    },
    "main": "./dist/pocketbase.es.mjs",
    "module": "./dist/pocketbase.es.mjs",

Currently, require() only searches for main, but main is not always the CJS version. In this case, it would be require('pocketbase/cjs').

Does it seem like a good idea to add this capability? I think this has become standard in node module resolution.
