REE's installer is interactive; if all installers were interactive (with a fallback flags system for non-interactive execution) then you would be able to customize them without needing a third-party program (homebrew).
Thew fewer third-party programs necessary to install an application, the easier it is to install and the less likely there will be errors. That is empirically true (based on my experience installing things on all 3 major OSs).
