Phones spend most of their lives powered on. You need to be required to enter a similarly good password to unlock it while the phone is running, or disk encryption has accomplished nothing at all.

Having a secure boot password and also a software-enforced pin to unlock accomplishes a great deal. And as a bonus, when a security measure is not grossly inconvenient you get more people using it.
