I'm wondering, instead, if we could convert strcpy() into this instead
of adding another API? I.e. convert all the places that warn (if this
were strcpy), and then land the conversion.

Perhaps not as strcpy is a builtin.

It might be easier as a cocci script.  Something like:

@@
char [] dest;
constant char [] src;
@@

*	strcpy(dest, src)

There are some additional test that needs to be added so that
only length(src) > length(dest) is reported.

Thanks for the ideas. I will think on this.
