The biggest significance of AROS 68K is that it could improve the experience of using classics and that is still the biggest "market" in the Amiga world. Most devs, most users. Simple as that.
AROS doesn't make much "sense" in the x86 or ARM world. It was fashioned over OS 3.1 and that makes it totally uncompetitive in that markets, except for the Amigans(most of which, again, own 68K machines). But on 68K it could become a new standard and like I said, it' where the biggest market is.
I'm curious about these markets you are refering to.
