Seems pretty trivial to support Python serverside. Python is very easy to run in a lightweight isolated container (and you can compile it to static executable).

Seems pretty trivial to support Python serverside. Python is very easy to run in a lightweight isolated container (and you can compile it to static executable). The game data that the engine makes available to the server side code looks pretty standard and doesn't look like a huge shim to maintain. You could even cross compile the Python to typescript for a simplified server side environment (typy for example).
