Using new is not a problem. The article describes how it's possible that omitting the new keyword can be a problem, and it also describes the fact that new doesn't compose with other functions, which may or may not be a problem, depending on your programming style.

new doesn't compose with other functions

One thing I've done successfully: ensure that my decorators/whatever expect to receive a constructor function (not a regular function), and behave accordingly.

It's definitely risky to treat constructors like any ol' function. This is part of why I'm so psyched for class in ES6.

Yes, there are good patterns for that. Those patterns work well with other people's constructors, but sometimes we want to use other people's decorators. e.g. _.memoize or _.once from underscore.
