As recently as 6 or 7 years ago I maintained some apps that forced 5.5 compatibility mode. Because they were poorly architected in a shitty framework and no one was willing to do or pay for or train for a rewritten version. They were finally migrating to .NET when I left. It was the govt so they are likely wrapping up that migration now.
Frontend developer here, please save me from my torment, thanks
