They have just released the new Titan V, which has Tensor Cores I believe. That would indicate that they do want to include them in non workstation/dedicated ML cards, no?
The Titan V is a compute card, the same way the Titan XP and Titan Xs were. Differing factors between them and the xx80[Ti] of the corresponding generation were memory bandwidth and capacity - gaming performance was nearly identical to the geforce. Titans are entry-level compute.
