You are asking the question the wrong way. Why should P-256 be offered without 
the --expert flag? It's not as if gpg wouldn't allow you to create a P-256 key.

Only experts will be able to make an educated decision between P-256 and 
P-384. It's good to give "normal" people less choice by default because more 
choice will just confuse them even more. Even having to choose between 
Curve25519 and P-384 will be too much already for people who just have been 
told that they should generate an ECC key.
