Go is not a dependency. Go is a compiled language, once you download the frankenphp binary you do not need anything else, whereas you still need php for yours.

The readme is fully ai generated so its not a great start, but I checked anyway and yes the only thing I agree with is the lack of X-Accel-Redirect which really bother me.

I know about safety I'm literally in the process at work of going through our app to check for this exact issue since we are moving to frankenphp. And it's quite easy, unless you did something REALLY WRONG in your app, it's just a matter of implementing the ResetInterface [0]
