Yes, it is perverse how intolerant devs tend to be toward old systems that perform valuable service and make a lot of money. There are some interesting ideas in those older systems designed to run with incredibly small resource constraints. That said, I think it's also true that incentives aren't always aligned when it comes time to port away from the entrenched environment, as these projects, if successful, constitute a real loss of income for the older devs.
