Your definition seems to be more demanding... which often is a good thing, urging Linux on to be better. Me, I didn't use the word "support" at all. I only said that I've done it on every one of my Linux systems since 1992 (except Raspberry Pi's). Yes, a little manual work was needed on the Windows side, but this was well documented and frankly not that hard. Since I've done it-- numerous times-- I'm not readily persuaded that it's impossible to do. Sure, it would be nice during the install process to simply click a button for "Yes, I want to dual-boot with Windows (or whatever)" and it would just happen. Yeah, I'd like that. On the other hand, what other (i.e., commercial) OSs support/allow/permit dual-booting? Given all the code for Linux is readily available to Apple and MS, it's much, much simper for them. The exact opposite is true for Linux developers. With VMs solid and much more useful and with deep market penetration, the need for dual-booting seems to be fading anyway.
