It’s not about killing microbes, it’s about getting rid of pathogens and spores they create. You can’t steam that away. For example, botulinum toxin can withstand up to +85C and botulinum spores can withstand boiling water. No dishwasher will make your stuff safe from botulinum.
Your toilet brushes probably don’t have anaerobic bacteria spores on them. To be clear, I think this is properly gross, but I also acknowledge that to some degree this is a marginally irrational preference for keeping food and poop separate. In all likelihood, there is no actual risk of disease from this practice.
Considering you can find traces of human feces on literally every surface inside a human home, I imagine you mainly need stuff like that for surgery, and surgical items are washed in what is, essentially, a dishwasher.

Hot water isn’t the only thing cleaning your dishes you know.
Yes, but none of the things inside the dishwasher are rated against fece transmited pathogens.
