We've had this feature launched for quite a while. Initially, I was reluctant to remove the feature-flag so that we could debug code paths for users on old versions of nix (which cannot benefit from the binary cache. IIRC nix < 1.17). However, in the time since I relied on this exactly once for some perf-related task, and not otherwise.
At this point, I think we should remove it, and even print messages to users about updating their nix version if needed.
How was it tested?
It compiles. I could do devbox shell in this project.
