Yeah it's great that it still works, and should!
That's not to say PHP isn't been overcomplicating itself & hasn't fully embraced why it's so succesfull and improved that part: it's easy & practical.
How can it be even easier? For instance even simpler hosting? With things like vercel, and app engine PHP isn't necessarily the simplest choice in hosting sites anymore.
A Vercel for PHP would be awesome.
