declare alternative main and ignore dependencies at the same time ?

[cancerberoSgx]

Is not clear to me how can I declare an alternate main.js and ignore dependencies at the same time with this proposal - if you tell me how I can PR and add the info in the README. Thanks!

It would look like this

"main": "main.js",
"browser": {
    "main.js": "main-alternative.js",
    "./dependency/x.js": false,
    "external-dep": false
}

how can I declare an alternate main.js ?

Map the filename to another file

how can I ignore dependencies ?

Map dependency to false
