Nixpkgs is Ok with all this, it does not import these overrides and have own separate mechanics for the overrides. Since cryptohash-sha512 package is essentially in the unmaintained state - I think it is not worth cleaning the Nixpkgs description because soon (on soon arriving 9.0) - it may be needed again in Nixpgs store, and to that time I hope we make a transiiton.
