I was part of a discussion few years ago where few people of a nearby university were very eager to implement modular learning, micro-credentials etc. They were discussing this in all earnest. Soon they realised that the logistics are just too much to handle this with the combinations that can happen with the modularisation and micro-credentials. And the evaluations becomes not just nightmarish but also very difficult to achieve. The realisation was that this sounds very good on paper but is a nightmare in practice.
