I think very fact it runs well (even as tcg-only emulator, on integer tasks at least) on 32-bit hosts actually good, and if 32-bit arm hardware can keep some codeways in working state for me - even better. But may be qemu as emulator and qemu as industrial hypervisor actually better to live separate lives?
