> Ahead-of-time BMI compilation is a non-starter. I didn't get why - one could imagine parallelizing BMI generation, then parallelizing "normal" compilation. The only issue I see is that you wouldn't know which BMI you'd need, so you would need to generate all of them (or regenerate those who are out of date), or specifically list those that needs to be generated in a build tool. Given how the rest of the compilation pipeline works, is that undesirable?
