I'm really giddy to see this being made use of by Docker / podman as the currently used QEMU based solution is slow as molasses.
In our case, the moment the M1 Macs came out, I have re-built our development images on ARM, but there are a few dependencies to proprietary software which is only provided for x64 and which I can't really support on ARM Macs ATM because running affected services through QEMU is no fun, especially as those are mostly about handling bulk data living in proprietary databases.
But if this comes close to what Rosetta can do on macOS, using it for those cases becomes feasible.
