Besides the "doesn't bother updating the passwords" point, this sort of "it's old so let's change it" attitude is unfortunately so pervasive in the software industry and I find it massively irritating because it's the same reason why a lot of software has gotten increasingly unstable over time. Instead of making only fixes and bringing a platform towards maturity they do the exact opposite, adding plenty of new bugs and breaking changes.
Keep in mind that the majority of people who need PHP (and technology in general...) have far more important things to do with their time than incessant trendchasing.
The saying about "known unknowns" and "unknown unknowns" is worth remembering too. The fact that a system has stayed working for over a decade should be enough to tell you that its creators did something right.
