That was the question. For instance, as far as I understand WSL generally does not work inside VMs (because WSL2 or 1 or whatever number transparently uses another VM itself). So I wasn't sure whether WoW64 does work inside VMs, glad to hear it does.

The claim was that you have great backward compatibility due to Rosetta ... except that due to 32 bit libraries that is not actually as useful as claimed. Not sure what your correction is?

32 bit apps were dropped in Mac OS Catalina in 2019, before the M1 was even hinted at. You had an x86 only Mac OS with no 32 bit support already.

Also 32 bit apps were marked as deprecated in High Sierra, some time in 2018.

Is that supposed to be a long time? If the claim is that you should get a mac for superior backward compatibility, then 5 years sounds very short.

for WSL2, with nested virtualization - it should

for WSL1 - virtualization is not used, it's more like syscall emulation
