From practice the Platform MLE is non existent in most cases except for places like OpenAI and maybe Google. The key thing not addressed here is that in software, the right levels of abstraction provide ways for pluralities of downstream tasks. That level of abstraction has not really been found in ML (yet). Every time you start making a larger system, researchers then have to onboard to that system and I find they really don't like how much time it wastes.
