Looks like it, for a manually added route (commonly named
"adding a _static_ route").

-static just sets the RTF_STATIC flag, but in src/sbin/route/route.c,
newroute() sets RTF_STATIC anyway (and has done since 1994) unless you
deliberately use -nostatic, so -static is a noop when you add a static
route. If you adjust a route added by some other method, you might
need it though.
newroute(int argc, char **argv)
{
char *cmd, *dest = "", *gateway = "", *error;
int ishost = 0, ret = 0, attempts, oerrno, flags = RTF_STATIC;
