Sure there is.  I believe that a scenario like the following would
be more useful that what we have now, and would not be difficult to
implement.

fantasy% cat prog.c
#include <stdio.h>
int main (void) { char buff[80]; gets(buff); puts(buff); return 0; }
fantasy% cc -o prog prog.c
ld: warning: this program uses gets(), which is unsafe.
fantasy% echo foo | ./prog
this program uses gets(), which is unsafe.
foo
fantasy% cc -o prog -lgets_that_does_not_print_to_stderr prog.c
ld: warning: this program uses gets(), which is unsafe.
fantasy% echo foo | ./prog
foo
fantasy%
