CUSA should have developed a separate AROS distro instead. Of course, under a mutual agreement with the AROS team. I don't like the idea of having a half-baked Linux-based distro in the name of AmigaOS.
Please stop blaming CUSA for not doing this: they just couldn't.
This has to do with the settlement between Amiga Inc and Hyperion, which basically forbids the former (or any former's licensee) to sell an 'Amiga' computer with a "similar to AmigaOS" operating system. Not only: it also forbids Amiga Inc (and Commodore USA and, probably, even Cloanto and others) from publicly support and advertise such "similar to AmigaOS" operating systems. That's all.
