Hi ISystem and IJobEntity both try to regenerate user code and promote using SystemAPI but it buggy and looks like it will always be buggy because it work on top of SyntaxTree. So each time new C# will be released we will be banned from using it because Entities code Regeneration will fail on it. Do unity have plans to create more robust API for entities where Code Generation Complement User code instead of trying to rewrite it? Do Unity have plans to support custom asset store code generator for ISystems and friends? Do Unity have plans to support Aspects outside of code ReGeneration context?
