This reverts commit65a333600d. This wasn't tested for correctness with something like fodwatch [0], and should not have been (self-)merged so quickly, especially without further review. It also resulted in the breakage of at least one package [1] (and that's the one we know of and was caught). A few packages that were updated in between this commit and this revert were not reverted back to using `rev`, but other than that, this is a 1:1 revert.

etcd
Upstream release cadence and support
The etcd project maintains release branches for the current version and previous release.
For example, when v3.5 is the current version, v3.4 is supported. When v3.6 is released, v3.4 goes out of support.

NixOS release and etcd version upkeep
Every major/minor version bump of etcd top-level alias in nixpkgs requires a notification in the next NixOS release notes scheduling the removal of the now unsupported etcd version.
After every NixOS release, the unsupported etcd versions should be removed by etcd maintainers.
User guidelines on etcd upgrades
Before upgrading a NixOS release, certify to upgrade etcd to the latest version in the current used release.

NixOS release notes might have instructions on how to proceed on upgrades.
