As an European, Classic Macs (and current ones) were just for arts/writting people. If you knew what CMYK was in order to print a newspaper, you were a Mac user. I emulated Mac OS 7 under XP times, and i was impressed that you could get far faster speeds emulating the M68k (and partially the PPC) compared to Intel X86 without any hardware accelerating chip (IntelVT) or kernel modules trapping X86 instructions running…
It was because of QuarkXPress and Photoshop. In the same way WordPerfect and Lotus 1-2-3 were dominant for business computers. Wish someone would try to create native MacOS classic on x86 hardware. There are so many Unix or Linux ABI compatible kernels like the recent Moss written in rust.
But if you are some software preserver, having a libre option to run legacy media it's always good for historical reasons. I am a daily libre software user but I emulate ancient machines with propietary stuff just for curiosity. As it not a personal computing device I find it fine. It's just an historical toy and not my computing device. And, well, if you want to create libre engines for old Mac games (ScummVM, SDL ports...), for sure you need to at least emulate the old OSes and run the propietary game in order to compare the output and correctness.
Also, it already exists "Mac" for x86. It was Rhapsody DR2 and it could run Classic Mac software and NeXT one too. It was like a blend of these two. OSX it's like NeXT Step concept 2.0, with few traces of Mac Classic. Qemu will run it fine.
