Lint was created in 1979, during the mid-90's we already had Insure++, Purify and others, ages before of the free beer alternatives.
Yet being free still doesn't help the large majority of C and C++ to actually use them, as proven at one of CppCon talks, where a tiny 1% of the attendees confirmed using any kind of analysers.
Your -second- third paragraph is, unfortunately, still correct though.
Maybe they are so skilled the need does not arise?
As for how well, usually conferences like CppCon have the top of the tops.
Belief that you are skilled enough to write C/C++ code that doesn't exercise undefined behavior either shows that you don't know what is undefined behavior or that you believe you are the best programmer to have ever lived.
