And why would they? PHP and JS weren't designed with their big use-cases in mind, even if their creators like to boast ("Always bet on JavaScript", etc.) People saw the alternatives as much better solutions. We had JSP and Java applets; those were the future! PHP and JS were just playthings for people who that couldn't grasp Java. Python had the luck not to be incepted as a small DSL for a specific problem. So it doesn't have the issues that PHP and JS face.
