I think we still want to have a warning in the case that the original was used, as there could be changes outside the version number, especially during debugging.

If you allow multiple instances of one version you return original problem that was related with $.checkArgumentType:

// in some library X
exports = function () {
  return require('bitcore-lib').Transaction.Input(...)
}

// in code that use library X
require('bitcore-lib').Transaction().addInput(require('x')()) // throw InvalidArgumentType
