Sounds like this introduced behavior changes. How did you evaluate if the new behavior was desirable or not? I’ve definitely run into cases where the missing fields were load bearing in ways the types would not suggest, so I never take it for granted that type error in prod code = bug
The most terrifying systems to maintain are the ones that work accidentally. If what you describe is actually desired behavior, I hope you have good tests! For my part, I’ll take types that prevent load-bearing absences from arising in the first place, because that sounds like a nightmare.
Although, an esoteric language defined in terms of negative space might be interesting. A completely empty source file implements “hello world” because you didn’t write a main function. All integers are incremented for every statement that doesn’t include them. Your only variables are the ones you don’t declare. That kind of thing.
