This is a very interesting change. I read this change as saying "As long as you follow the Enhanced Typsetting standard you'll be fine. But if you deviate from that standard then your ebook will fail when you test it on KP3 and will also fail if you upload to Amazon". The one saving grace from his change is that you can now test your ebook in KP3 and if it fails then you will explicitly be told why it failed in the KP3 log. That's not so bad for techy folks who work with epubs and html. But how are the Word uploaders going to cope with these techy error descriptions?

I hate to say it, but there could also be another good reason why Amazon is now forcing indie authors to follow the Enhanced Typsetting standard. Whenever you create an ebook using Kindle Create you will get a KPF file that will ALWAYS pass the Enhanced Typsetting standard without fail whenever you test or upload. So is Amazon KDP, indirectly and sneakily, now trying to force indie authors to create ebooks using Kindle Create with their new ET policy? Just a thought. Personally, I would always prefer as many upload formatting options as possible.
