The downloadable edition of Amiga Forever only has 1.3 and 3.1, but costs half as much. Still, it would be fun to have 1.0 and 1,1. When I bought my A500 back in 1989, I started with 1.2. I think that the fighting over UAE is regrettable, but I can understand it. I think that it comes down to hardware vs. software.
Some people are fans of the efficient OS, others are fans of the hardware.
I remember about 8 or 9 years ago, quite a few Amiga users that I knew didn't even use Workbench, and just used CLI for everything. If it looks like an Amiga, feels like an Amiga, and runs Amiga software, its an Amiga. Sadly, the OS may be the Amigas best chance of surviving. If new Amigas had been produced running the PowerPC, we would need emulation to run our 680x0 software. We may not get any new Amiga hardware.
