How ignored modules shall behave when imported from outside

[yurydelendik]

Spec says:

You can simply prevent a module or file from being loaded into a bundle by specifying a 
value of false for any of the keys. This is useful if you know certain codepaths will not
 be executed client side but find it awkward to split up or change the code structure.

If I want to disable e.g. some local module "./server/only.js" inside package "sample". The sample/package.json fragment will contain:

"browser": {
    "./server/only.js": false
}

However what if I decide to this module from the external package, e.g. an external package code has:

var only = require("sample/server/only");

Shall the packager replace the only with empty module in both places or only inside of the "sample"?
