If they can define a useful ABI that manages to include lifetimes, that might just be enough of an improvement to get people to switch over from assuming the C ABI everywhere.
The problem is that both Rust and Go are huge. The compiled binaries are bigger and the compilers themselves and slower and more resource intensive. The current benefit to C is that is lean and compiles quickly.
C is definitely still king, but I wonder if crABI will eventually be able to dethrone it:
