Browsers shouldn't have an install. Can we stop half-baked HTML XML syntax at this point?

I forsee abuse of such:

    const button = document.querySelector('install');
    button.addEventListener('promptdismiss', () => {
      console.log('User dismissed the install prompt but forcing installation of adware, malware and bitcoing mining anyway');
    });

This isn't possible, the PWA install flow is managed by the browser.
