I have seen that managers decided to let something rewritten in C, for various reasons, mostly to set the language culture.
It seems obvious to me, that no C++ coder would switch voluntarily to C, since then he would reminded of the features he is missing every day glaringly.
So either you switch to Zig, Rust,... or (if you are finally fed up) to a functional language or you choose to code in a certain subset.
