Any Way to Do This Without Specialization?

I'm pretty certain this is the exact use-case for specialization, but can any super-smart person find a way to do this without specialization?

I'm trying to find a way to automatically implement Component for any Rust type without boilerplate, but still allow explicitly implementing Component manually. Related to the bevy stable TypeId issue.

use std::collections::hash_map::DefaultHasher;
use std::hash::{Hash, Hasher};
use std::any::TypeId;

struct Component1;
struct Component0;

impl Component for Component0 {
    fn id() -> u64 {

trait Component {
    fn id() -> u64;

impl<T: 'static> Component for T {
    fn id() -> u64 {
        let mut hasher = DefaultHasher::new();
        let id = TypeId::of::<T>();
        id.hash(&mut hasher);

fn main() {

Ah, nevermind, found a better solution for the particular application:
