It's a deliberate choice to not inherit the "developer mode" to child processes. If someone would like an inherited mode, I would prefer to add a new PYTHONDEVMODE=1 environment variable, since it's more natural to inherit environment modes.
It's the same for -W ignore vs PYTHONWARNINGS=ignore.

Perhaps PYTHONXOPTIONS=dev? That way it would more directly parallel the -W vs PYTHONWARNINGS arrangement.

The PYTHONXOPTIONS/PYTHONDEVMODE question should be split out to a separate tracker issue.
