Classes and exams in a PhD programme? I've never heard of this anywhere - I had no idea that was a thing in the US.
There is an ugly trend in the UK to having "credits" for attending workshops as part of your "personal development". You basically have to go and sit in a workshop pretending to listen to someone talking about academic writing so that some admin can tick a box. Considering even postdocs and RAs have to write reports on how their "personal development" is progressing I don't think the powers that be will be happy until everyone can be placed into a spreadsheet.
