I don't buy the argument that having a bunch of vendors extend the ISA makes it more secure. I think we would end up with an ecosystem with a lot of custom extensions and functionality that will end up exposing more attack surfaces and that would make it difficult to know if your device is affected or not.

I think a lot of people are talking about "closed source" security as in nation-state level actors and "backdoors": https://www.csoonline.com/article/3220476/researchers-say-now-you-too-can-disable-intel-me-backdoor-thanks-to-the-nsa.html https://www.csoonline.com/article/3220476/researchers-say-no...
