Assume we are building a cruise missile flight computer. I have enough ram for ~100 hours of flight if we never clean up any allocations. I only have enough fuel for 8 hours of flight on a good day. Why do I still need a garbage collector? All I need is a garbage generator.

I've spent weeks on this exact thing. I cannot get it to work. This gets me back to the first party

ZGC does not stand for zero. It stands for Z Garbage Collector. It's a next-generation GC implementation for OpenJDK that focuses on low pause time while supporting very large heap sizes. It does not "not collect garbage". You could try using https://github.com/kkokosa/UpsilonGC and seeing if it still works. At the end of the day for anything performance-related you can just write code with manual memory management with RAII patterns via IDisposable on structs and get code that performs closely to C++ or Rust. It's also necessary to understand if this is a good idea at all - most of the time you do want to just rely on GC.

It isn't trivial but it is supported. Here is an example [0] toy. I am not aware of any production grade replacement GCs for .NET out there currently https://github.com/kkokosa/UpsilonGC

Games would need alternative GC optimized for low latency instead of maximum throughput. AFAIK it has been possible to replace the GC with alternative implementation for the past few years, but no one has made one yet. EDIT: Some experimental alternative GC implementations: https://github.com/kkokosa/UpsilonGC https://www.codeproject.com/Articles/5372791/Implementing-a-...
