Thank you.
Our approach is to provide a stable base system, not to maintain wizards for everything. We provide some basic system configurations - for setting display, to install into NAND / eMMC / USB / SATA, to install Rpi monitor etc ... by default. The rest ...
I maintain one after-install script for installing various services:

This is similar but it is a separate project since you can install this virtually on anything that runs Debian / Ubuntu and clones.
