I'm sorry but the way they interrupt the flow so many times is ridiculous. It would take minimal changes to make this flow non-disruptive but Apple wants users to drop off as much as possible during installation.
Some of this interruption is to scare off users who will absolutely fuck up their phones with bitcoin mining apps, given the opportunity
You can argue whether this paternalistic approach to technology is appropriate for the entire userbase, but there are definitely a number of cases that Apple is doing a genuinely good thing for their users here.
There's similar number of steps to trust a third party root certificate, or a set a third party DoH provider. Do you also think those tasks should be 1click as well?
At some point, you go past squinting your eyes very hard straight into non sense you know.
