The repo does not make it clear, but Apple ships Linux builds of Rosetta 2 that can be used inside Linux VMs on apple silicon hardware [0]. With some patches (or so I'm told) it can be made to run on non-apple-silicon arm64 hardware.
Even if it's not fully decompiled yet, it should be possible to relink the decompiled subsections into an original binary.

No. Even the decompiled version is incomplete - there's comments all over it which signal missing code like "could not recover jumptable ... too many branches". The "refactored" version is wildly speculative - it looks more like a very clumsy attempt to write a new translator than to reverse-engineer an existing one.

With the huge caveat that the generated code will expect TSO to be enabled, and may malfunction on non-TSO ARM systems, particularly when running multithreaded code. (Most ARM systems are non-TSO; Apple Silicon has a MSR to enable TSO.)
