I might be wrong but I don't believe that WM_HINTS is the issue.
emacs already has input_hints->input == True and input_hints->flags&InputHint but still does not get focus.

Here is an app that I wrote that does this. But as I said above, at least emacs already has the appropriate hints set so this doesn't work for emacs.
#include <X11/Xlib.h>
#include <X11/Xutil.h>
#include <stdio.h>
#include <stdlib.h>

int main(int argc, char **argv) {
Display *display;
Window window = 0;
XWMHints *input_hints;
if (argc!=2) {fprintf(stderr, "usage: set-input-hint <id>\n"); exit(-1);}
if (sscanf(argv[1], "0x%lx", &window)!=1) {
fprintf(stderr, "id must be in parsable by 0x%%lx\n");
exit(-1);
}
display = XOpenDisplay("");
if (display==NULL) {fprintf(stderr, "can't open display\n"); exit(-1);}
input_hints = XGetWMHints(display, window);
if (input_hints==NULL) {
XWMHints input_hints = { .input = True, .flags = InputHint };
XSetWMHints(display, window, &input_hints);
}
else {
input_hints->input = True;
input_hints->flags |= InputHint;
XSetWMHints(display, window, input_hints);
XFree(input_hints);
}
XFlush(display);
}
