Yep, thanks for that pointer, I'm pretty much doing that, except on Debian Linux. I was surprised there wasn't a Minecraft server or client out there that let me control through an administrative layer a toggle switch to let players interact exclusively through the Python interface, or also let the keyboard and mouse drive input, or exclusively the keyboard and mouse ("classic mode", so to speak). I'm also surprised that no Young Lady's Primer-style worlds of interlocking puzzles haven't been constructed, or even started, that I could locate through searching. There are highly episodic one-shots, or relatively brief arcs, but I haven't seen any really involved worlds accreting complex storylines, continuity, and character development as the children work out puzzles teaching and reinforcing concepts and skills with them. Once children get engaged into a story, at least my son and his peers get extremely motivated to solve the puzzles and they fatigue on failure far later, like an order of magnitude or longer.
