compiled.php missing from Lumen

It seems that Lumen does not use compiled.php like Laravel does. It also seems like artisan optimize does not exists as well.

Since Lumen is meant to be light weight it seems that continuing the compiled.php approach would make the most sense. Is there a reason that this was not implemented?

If I want to move my project over to production, what is the best way to get a compiled version where I wouldn't have to include the vendor folder in my app?

Thanks
