By design Calamares is very customizable, in order to satisfy a wide variety of needs and use cases. Calamares aims to be easy, usable, beautiful, pragmatic, inclusive and distribution-agnostic. Got a Linux distribution but no system installer? Grab Calamares, mix and match any number of Calamares modules (or write your own in Python or C++), throw together some branding, package it up and you are ready to ship!
