Cache all of .julia?

[maleadt]

We now cache very selectively, but I wonder if it wouldn't be better to cache all of .julia, speeding up registry check-out and package installation. Or would that hurt reproducibility?

I'm not positive on this, but I don't think that this would hurt reproducibility at all. I think that without a manifest checked in, the dependencies are resolved from scratch regardless of what's on disk. And if there's a manifest checked in, then it defines the exact version of everything itself.
