> will still be installed as an option you can select in the UEFI firmware settings. Exactly. But to the first time user, their linux has disappeared, and they have to go look up what happened, then they have to figure out how to get into their motherboard's boot menu... and by now, you lost 99% of users. And I recently had my (systemd-boot) Windows entry fail on the linux side and had to go in and fix it. Not sure about GRUB these days. This is a microcosm of linux. Things just work if you go in and fix this little thing here and there, but most people don't do and won't do any kind of maintenance like this.
