[Rusky]

That's not a very meaningful distinction to make- Rust doesn't even have a standard right now. Besides, -fno-exceptions is quite useful today, not just because of 90s compiler deficiencies, and is pretty well-supported by compilers.

The existence of -fno-exceptions means that library authors either using the language as intended, and accept losing a portion of their potential user base, or write less-than-optimally elegant and clear code, which punishes everyone, so a few can turn off a core feature of the language. It fragments the community.
