An example where this matters is tethering right now. My android phone won't tether. It's an unlocked android phone bought independently of the carrier. But it won't tether the connection to another device as my provider has a flag that this is not supported and android due to pressure from carriers obeys this on all phones, even non carrier locked phones. Of course I can just swap the sim into a dedicated tethering hotspot and it works. But esim will soon fix that as esims are tied to the phone.
