So there might not be too much room to improve. There could be some room to improve for things like "custom ... memory pool" since .NET Core has ArrayPool [2] built-in. But I can't tell if the spirit of that rule is "don't implement pooling" vs. "you can only allocate memory in the standard ways provided by the runtime."
