That's great if you're maintaining your work. I think a somewhat broader problem here is the number of unmaintained PHP webapps/sites, commissioned by small business on short contract jobs and then never touched again. I'm familiar with this phenomenon because a decade ago, I used PHP for contract work. Some of my work from this time is still running, seemingly unaltered. I've gone back to clients over the years but they treat me like I'm trying to shake them down. Even if you make it clear you don't want to do the work, it rarely has a good outcome. Of the dozen or so clients who were still running my output 10Y+ after the fact, one took it offline, the rest blanked me. Now consider how many PHP contractors exist out there doing scrot jobs for SMBs? How many of these crappy little sites exist? Millions? Hundreds of millions? Do you think it more likely they're going to spring for upgrading/replacing all this? Or that 5.x is going to stay exactly where it is, indefinitely? They're not going to "sweat it"; they only care about financial outlay.
