So I was thinking about something similar to this in the sense of a language where syntax was extendable but with making different choices. I was interested in forming some sort of base lingua franca with additional composable dialects that are available per translation unit. Imagine if you could take go know for sure you don't have any concurrency in a section or the memory management section is missing so no worries about memory management. Increasing expressiveness but also reducing cognitive load to the calling code and its interfaces and nowhere else. Want to run very complicated domain specific code and not have the guy who designs the webserver know anymore than what is nessecary to rout it great. Want to add hot code,io, complexity annotations in the code, Great(Obviously this isn't free you need good tooling and to do sampled profiling and for complexity you need to make choices about what code is complex, etc.But if we're dreaming why not dream big.). Metrics,Explicit resource bounds etc. In this context for the things most people would want i.e. concurrency you would have a readily available dialect that fits 80% of use cases which would be infrequently changed. I don't know if that makes much sense in what you have in mind but I did find what you're doing interesting.
