   Presumably the reason venv was added was to solve some problem (maybe mixing up of dependencies or something like that). Just falling back to not using it would cause it to (non-determanistically) exhibit the same issues that adding this was trying to solve. 
   
   Some alternatives would be to make it explicit whether venv should be used (either opt-in or opt-out) or make venv a requirement for Beam (if the user pre-installs beam) or at the very least give a clear error (e.g. "venv is required but not installed in this custom container).
