But such a large scale user would quite likely want the meaning of "core" in the respective vendor's sense, i.e. CPU scheduling on AMD (as not being affected by the various HT leaks), and core scheduling on Intel. Due to AMD Fam17 now actually calling the thing HT too, in fact such installations would likely want _different_ options when the primary goal is security, and a secondary one is performance / throughput. Otoh I guess this is going to be our default eventually, i.e. no command line option ought to be needed to achieve this.
