Very few do. Just look at Symfony's complexity , the devs managed to shove proxies into the IoC container to "lazy load services" so you could inject them into the controller class constructors without actually instantiating them until you call a route handler's controller instance method... Using complex class hierarchies in PHP has a big cost, while "raw PHP" barely executes the underlying C code. To be fair people using heavy frameworks come for the battery included first, not really for the speed of the router. And since devs want more batteries, it's unlikely it will get faster.
