Yeah, I understood your idea. So we parse config_value directly to 
static int num_threads; /* old use_threads */
And use it internally in builtin/grep.c. I think you are right.
Looks like grep_cmd_config() is the right place to parse it. Something like:
--- a/builtin/grep.c
+++ b/builtin/grep.c
@@ -267,6 +267,8 @@ static int wait_all(struct grep_opt *opt)
 static int grep_cmd_config(const char *var, const char *value, void *cb)
 {
        int st = grep_config(var, value, cb);
+       if (thread_config(var, value, cb) < 0)
+               st = -1;
        if (git_color_default_config(var, value, cb) < 0)
                st = -1;
        return st;

What do you think?
