IMHO agreed. I believe that there is a perceived convergence of "needs" between (call it...) more-mobile personal linux and _virtualised_ server linux. If we can create a linux VM in under 5 minutes, "we" expect that it will boot-up without the sys admin's intervention. Then "we" expect that we can migrate it to newer hardware without manual reconfiguration.
But returning to PHP: If apps are developed without real separation between user interface and back-end, then the back-end will be victimised by the relative and inherent instability of the front-end. The web servers then really become part of the front-end and must be handled as such. I would argue that this lack of separation between front-end and web server is a feature of the WWW and its protocols, we cannot escape it. So no surprise that most data centers leave the web servers outside or mostly-outside the network perimeter.
