SDF font rendering has been around 20+ years though? Valve really popularized in their 2007 SIGGRAPH paper and Chlumský developed MSDF font rendering in a 2015 thesis.
If you're paying the cost of serializing/deserializing the whole game state around every reload of the worker, why bother with the unsafe type-erased PersistWrapper (which still requires you to restart the host any time the game state struct changes)? Just keep the game state entirely on the worker side, and have the host instead pass, say, a &mut dyn Write to the before/after_reload functions. The old worker can write whatever it feels like there, JSON or whatever else, on the assumption that the new worker will decode it somehow. The new worker then stashes the deserialized game state in a static Mutex<GameState> during the after_reload hook and the actual hot_update function goes back to taking just the host trait object. The big advantage here is you can change the game state struct during a hot reload as long as the deserialization can handle it. With JSON, for example, adding new fields to the game state struct would be perfectly fine: old fields still get deserialized and new fields get default initialized.

I doubt it's Cleartype, the close up photo of the U3223QE show all subpixels uniformly dimmed on the fringes. The post also says the monitor is attached to a Mac mini and a previous post about OpenSCAD has a screenshot with MacOS window decorations.
I would think leaders sometimes not following their own codes of conduct is the strongest argument in favor of having them: yes, they are obvious to everyone but they are also evidently easy to forget in the heat of the moment. It's a standard of behavior to strive for not one statically attainable. Reminders are needed and that's the purpose their deliberate codifying serves.
In fairness, Emacs has long had cua-mode for rebinding C-c, C-v, C-x, and C-z to copy, paste, cut, and undo, so at least those changes are not too radical.
