Lets face reality. 68k Amiga is for nostalgia purposes only, not too much real work will get done on those computers (even Vampire accelerated), as the software ecosystem is just too old (ie. no modern web-browsing, no modern office suite, etc).
Another reality is x86 is dominated by Windows... and Linux has cornered the free market.
That leaves ARM and Raspberry Pi devices. Currently they run Raspbian (Linux); however, even stripped down, the OS is a bit heavy. This is where Amiga OS (ie. AROS) could potentially make serious inroads.
AROS running on the Pi, and there are millions of Pi's out there, gives the AmigaOS another chance to become relevant again. Apparently, there is a version of AROS that runs hosted on the Pi and runs pretty well; unfortunately, that
version seems to be paid. But AROS is OSS licensed, so anyone who purchased the paid version would be able to upload it.
P.S. I fully support open-sourcing the current closed source software on the Amiga too! I would just like to see work put into making AROS viable in the Pi as well! =)
