True. I don't use Windows either normally. I have one R&D system which has Windows installed, and of course installed first because I would never trust the Windows installer to leave a Linux installation untouched. It has a disturbingly small ESP. I could just fit 2 kernels + initramfs there. I did not even try to repartition it because I would not be surprised Windows either breaking or reverting some changes at next boot. For me that system is not important and I did not want to spend a single extra minute on it. But obviously someone had to spend a lot of time to cope with that unfriendly system.
