Yeah, but then we're just haggling. If you know how to change the belt on your car and already have the tools, it's different from when you're stranded with no tools and no garage and no belt.
Configuring a web server is a low-difficulty task that should be available for any good software developer with 3 days to study for it. It's absurd for a developer to need to configure a web server, but insist on paying a large rent and cede control to some 3rd party instead of just doing it.
I bet you could figure out `apt install nginx` and a basic config pretty quickly, definitely faster than a web dev could learn game programming. “What do you mean, I have to finish each loop in 16 msec?”
