I agree that searching for "unsafe" is easier, we should have this in C too. I have some local patches to GCC that emit diagnostics for some things which are unsafe in C and were GCC does not already have a warning. I think the culture is an important point, the question is how this scales when the community becomes larger and then the share of well-paid enthusiastic Rust early adopers make way to tired, less interested developers that inherit a lot of code and have to get some things to work with limited time...
