This no longer hinges on app.debug because it creates confusion for devops engineers. This is based on three independent reports coming from app environments that use a reverse proxy. The engineer will follow the proper security instructions by disabling debug mode, which in turn creates an infinite redirect loop when opening the back-end area, only to leave them scratching their heads
Ultimately it is the web server configuration's job to handle the enforcement of HTTPS, the app no longer enforces it as a strong opinion, but we still keep the setting available as a convenient security check for standard environments that do not use a reverse proxy
runInternal has been removed because we do not want to blanket our response logic over every single response, only the happy path. This is because it is impossible to remove. So it is better to take the inverted approach, where if you want the CMS' headers in your custom response, add them yourself. This becomes easy via the new makeResponse() method
