The ability to quickly turn off the phone is useful when you need to activate a long password so that you cannot be forced to use your fingerprint to unlock it.
If you are in a place where you can be forced to unlock it with your finger they'll force you to give out the password too, it would probably even be more painful.
The only place where you would not want to use biometrics are western* countries which would allow the police to compel you to give out your fingerprints to unlock the phone.
With the exception of the UK in which not giving out a password or decryption key in the course of an investigation even if you are not the suspect of a crime can land you 7 years in prison these days.
