It has the advantage of running on ARM, which is still easy to obtain. I also think there are OSs for the Atari ST that are open-source and still maintained, but unfortunately, no 68K processors are easy to come by.

That is true.

Several ST OSes have FOSS recreations. DR's layered, cleanly-layered design lent itself to piecemeal re-implementations.

Aranym runs AFROS, with multitasking thanks to MINT, which is a compilation of FOSS bits:

Aranym needed a ROM and the devs wrote a skeleton with most stuff stubbed out. This has led to a full scale ST TOS recreation, with the original's limitations: it's single-tasking and so on:

The FreeMINT OS is also FOSS:

MagiC was a 3rd party commercial re-implementation:

But there's no new 68k hardware. Emu68 is working on a JIT runtime for the Raspberry Pi:
