The vm1_ prefix and vm2_ had had special meaning until 820ad9cb1d72d0897b73dae282df3793814b27e8 and 12068aa4e980ab32a0438408a519030e65dabf5e. AFAIK there's no special meaning in vm3_ prefix. As they have confused people (like "In `benchmark` what is difference between `vm1_`, `vm2_` and `vm3_`"), I'd like to remove the obsoleted prefix as we obviated that two years ago.
