It would be the most beautiful, elegant, well-designed and thoroughly hardened network I'm certain. I get it, the software I'm complaining about was designed for profit.

The point I'm trying to make is imagine you have to tell a customer that they can't keep using the network design they have, which fits their requirements almost perfectly, because it's too much burden for your network engineers to maintain. Instead, the customer can use this other network design that is suitable for the average customer. So it works, but not as well as before, and the customer will probably need to find some workarounds or shift other processes to accommodate. It's just shit.
