This reverts commit 361139c574, reversing changes made to 77ee91f1d3. This broke tests in some go packages, and at this point I don't want further delays from figuring out what's wrong. This probably won't make it to 22.05. Example failures: https://hydra.nixos.org/build/176551928 https://hydra.nixos.org/build/176546993 but I think there were more among https://hydra.nixos.org/eval/1762178?compare=1762151#tabs-now-fail
