Dear All,
Thank you very much for the thoughtful and detailed discussion. I have learned a lot reading all your comments. There are legitimate concerns which I had not even thought of (like the idea of "future proof" mentioned by Alex). From the Github thread mentioned by Nathan, it appears a lot of the relevant issues have already been discussed in great depth early last year. If I have any more suggestions (mainly in my capacity as a webwork user/instructor) in this context, I will perhaps start a new thread under "New Features and Development Ideas". Thank you very much!
Best regards,
