I think anybody should have the right (or the claim) to use the entire workspace of a CNC machine you buy (I have this claim). Especially when you have a gantry-style machine that allows tiling of larger workpieces due to the front and rear being completely open. But you have to think of swiveling toolsetters and tool changers with [swivel arms](https://commons.wikimedia.org/wiki/File:Chain_type_changer_and_arm_with_two_grippers.jpg) then 🙂 (or an entire tool magazine [that slides out of the way](https://www.youtube.com/watch?v=ZeOUdosoEBM))

Regarding homing X & Y, my opinion is that going the [proximity sensor way](https://forum.onefinitycnc.com/t/controller-software-tool-change-location-0-0-g54-g55-g56/10052/14) solves the problem but you can still have a fence to position your tiling workpiece without zeroing X & Y.
