Convince me: Backpacking Bidets

I'm mostly a day-hiker. I'd rather hike farther than carry more.

I'm slowly Passage-hiking the Arizona Trail, and there are stretches where overnights will be unavoidable.

I'm not going to cut down my toothbrush, but I do want to carry as little as possible.

I hear positive things about backpacking bidets, but the concept seems (to put it delicately) "optimistic" to me.

I may attempt the "try it afterwards in your shower at home" advice I've seen elsewhere, but that seems...gross.

Am I missing something, or is my risk tolerance misaligned with the reality of roughing it?
