Yes, I thought about that, and which is why I'm just running this as a pilot for this quarter to see how it goes and I'm not particularly attached to it if feedback/results are mixed. But that said, there are real constraints on my ability to supervise students with in-person examination, but that is more a problem with how my society funds and cares about education. We are forced to take approaches that 'work at scale', hence experiments like this. But truly, reception was positive when this was introduced, because students too want to be held to a good standard and don't want others to get credit for not doing the work toward achieving the learning outcomes like the most honest ones.
