The problem with this is imho that for a C replacement it doesn't offer enough to C programmers to switch.
If you're comfortable with C you will stick with C and benefit from it being the lingua franca, and not struggle to find support or talent.
This is true both at work or OS.
As a very talented C dev told me, I can see the point or go or Rust that would solve some of my issues, Zig while being an improvement doesn't solve any of my real pain points.
