The old one-size-fits-some approach is as pragmatic as it gets. Society's education needs have grown beyond what the old model can adequately service. We need new solutions that don't cause regressions on the old solutions.
You're right to protect your existing solution against regressions, and there's value in revisiting old topics in the new discussions, but you're not going to constructively contribute much if you're unwilling to engage with why so many people feel the need for something different in the first place.
I actually completely agree with everything you wrote. I'm also very familiar with the ongoing battle between education and training.
What I'm talking about is expanding options to meet additional education needs. Since universities are a shared resource, any solution must be carefully designed to preserve the ability to continue providing existing services. That's difficult to achieve, so I understand the obstructionist response.
All I'm saying is that if you position yourself as an obstructionist, don't be surprised when you're treated like one.
Your response does a pretty good job demonstrating the internal challenges universities face. The interest in making a change was motivated by unmet needs, and it's not going away until those needs are met. The only way to deal with people who won't meaningfully engage in the problem solving process is to go around them.
