I generally prefer the latter term, because what Rosetta produces are not standalone executables, they're incomplete. I don't know how often the happy path is used, but Rosetta can always be observed doing work at runtime. JITs are great and Rosetta 2 is incredible! I just can't imagine it working over any sort of shared filesystem, that would add an incredible amount of latency.
