Exactly this. The onboarding process is simple but the total cost of ownership expensive. I ended up having my older mobile phone with me like a token device and will migrate its keys when I have time to do that. I was even confused by the Samsung migration using the USB OTG connector since doesn't clearly states that some stuff is not migrated.

I hate when you need to put your brain in sysadmin mode instead of disconnecting it expecting a process that just works.
