You know, considering the range of options that can be seen in the comic, they might want to keep a close eye on the kind of chassis that might be offered. I can easily imagine a story line where the person in charge checks and sees that in fact, yes, there is a newer chassis available, and they can shift her into that. Only to end with Roko carrying May to see her parole officer, as a toaster.
I think she'll stay with an anthropomorphic chassis, but there are other options. Toaster, assembly arm, forklift, sentient door,...
