Problem is, you’re mixing a number of different concepts into a nonsensical claim.
Exec as an “execute a string as a language instructions” is nothing new nor unique to PHP. Ruby on Rails, for example, uses it in a controlled manner to generate methods on ActiveRecord models.
Exec as an “replace this process with another process” is old news again. It’s not even language specific.
Popen/spawn family (which seems to be what you alluded to) is, once again, nothing new and is used everywhere.
I’m sorry, what?
Turns out arbitrary code execution is actually great(!)
it does not have to be arbitrary my dude
