It is hard to see a benefit having a binary integration of Python in the flightgear core. Using python to get/set properties and run fg-commands is already possible without any c++ integration.<ref>{{cite web | |||

One major concern with the FGPythonSys integration is that it introduces an unpredictable (w.r.t. timing) step in the main loop getting us on step further away from constant frame rates.<ref>{{cite web | |||

Instead of adding just-another-feature we need to strip it down to getting a fast and constand fps rendering engine. Everything else needs to run outside the main loop and has to interact with the core by, say HLA/RTI or whatever IPC we have.<ref>{{cite web | |||
