There are select use-cases where hash randomization is undesirable, having a CLI option to switch it off would be very helpful.
One example would be packaging, where hash randomization will make the bytecode unreproducible.

Currently, we have to set PYTHONHASHSEED to a constant value. Having a CLI option (lets say -Z) would allow use to do

  python -Zm install artifact.whl

instead of

  PYTHONHASHSEED=0 python -m install artifact.whl

Which is something that I have to do lots of places.
