I really do not agree with that, now that can work with small websites you don't care about and just not going to do maintenance.

but in my experience, the technical debt will be a big problem later on, if not a total deal breaker. This is a problem found a lot in html integration, and jQuery new comer that push one millions of events in the dom.ready

Unmaintainable mess = hours and hours of lost work

I find that the easiest and cleanest solution is generally the better, I always try to not over engineer my code.
