This only really applies to languages that don't check this at compile-time. I don't consider compile-time errors a foot gun. I mean, it should be impossible for that kind of bad code to ever get merged in most reasonable CI/CD processes.

No? This happens in any language that has keyword args.

If I delete/rename a field of a class in any statically checked language, it's going to report a compile error, and it's still a breaking change.

Sure, but it doesn't actually matter because this can't ever manifest as a bug. Your PR will just be rejected, which to me, is correct behavior.

Typically when you're changing a name you're changing behavior, too. This isn't just something we should let slip under the radar, otherwise bugs can actually manifest.
