When one's person creativity causes another a lot of work and unnecessary problems, then we have a problem. And a huge problem at that. This is exactly the case.
How does the existence of another programming language cause a lot of work and unnecessary problems? Like, the existence of, say, Zig, which I haven’t used, hasn’t seemed to cause anyone any problems.
All it takes is for someone to "get creative" and write a mission critical piece of software in their newly invented language, and then one gets stuck deciphering that mess when things go awry, which they always do.
Can you not see the consequences, or have you never had that happen to you?
