Neil from the Buck2 team here. I think your points are pretty much spot on - everything we use internally is battle tested, everything we don't is less tested. We've tried to use that to our advantage by making as much as we can a

We schedule tasks mostly using tokio - without any particular care. It's mostly good, but occasionally causes some performance headaches. I think in the fullness of time we might need to invest more in careful scheduling.

Thanks for the comments! There are two levels at which you could make Buck2/Bazel compatible: * At the BUILD/BUCK file level. I imagine you can get close, but there are details between each other that will be hard to overcome. Buc

The old GHC build system did do everything in 3 phases. And they were pretty magic phases. It's not clear there's any upper bound on the number of phases, and maintaining each phase separation is very tricky.
