How would it not? It’s no different than tutoring. I pay the website a monthly fee (which probably needs to be an IAP) but the payment to the babysitter could continue as-is via bank transfer/ideal.

Ah, I see. I was intersecting "real-time experience" with Apple's previous "digital goods" and thinking "real-time experience that happens digitally" (which tutoring students, medical consultations, real estate tours, or fitness training all can support), and I quickly wrote off babysitting as something that can't happen digitally. I'm much less confident now based on how you're reading it.
