Greetings,

I notice that the initialization mechanism for the runtime simply calls Py_Initialize or Py_InitializeEx. There's currently no clear way to, for instance, pass the -I flag to the runtime to set up an isolated config, without controlling the process environment variables. This has some security considerations for my desired use case; the concerns are not unmanageable, but the workarounds are a little clumsy. More generally, this seems like the kind of useful option that would couple well with an embedded python environment (e.g. through Python.Deployment) which I suspect constitutes a large percentage of pythonnet use cases.

With support for Py_InitializeFromConfig and some means of generating the PyPreConfig and PyConfig objects (effectively just support for some of the security-conscious options on the runtime such as -I or -P), I think this would be a lot more straightforward. If there's some technical considerations that would make this challenging, I'm curious to hear them: since pythonnet is open-source, I may take a crack at patching in an overload to the PythonEngine.Initialize that lets me specify some of the security-conscious arguments for isolated configs, and I'd like to know if anything like this was attempted or considered in the past.
