I can't say if it's a joke or if you are serious. But if you like an installer, there's manjaro.
Personally, I think install shouldn't need a click-through installer: it should be done by a commandline, to have a finer control over all the details.
With Ubuntu, I only used the installer iso to type Control-Shift-A to get a terminal, install rsync and do my tinkering.

Manjaro is not Arch. My comment was a criticism of Arch Linux, not Manjaro.
Or how can you mount the efi partition to new systemd location /efi instead of /boot/efi (ex: if you're not using grub) without breaking the install?
There are just too many choices for too many people. It's best not to play, and let it be a commandline problem. You rarely have to reinstall without another OS or boot media, so doing a chroot and copy-pasting the right commands (or rsync or untar a working master image) is just simpler.
