I see your points.
Looking at the MAT_242 incorporating kinematic hardening, it appears to me that the hardening of the material is inherently considered through the Yoshida-Uemori coefficients (unlike the MAT_133 where you could input the hardening curve separately). I would suggest you look at the Yoshida-Uemori equations to investigate if the strain rate sensitivity can be considered from there.
