Why is ECC (Eliptical Curve) an `--expert` feature in PGP?

Eleptial Curve is now included in PGP. However when I run gpg2 --full-gen-key, I get

Please select what kind of key you want:   (1) RSA and RSA (default)   (2) DSA and Elgamal   (3) DSA (sign only)   (4) RSA (sign only)  (14) Existing key from card

It's only when I run it with gpg2 --full-gen-key --expert that I get the option to generate an ECC key,

Why is that ECC is only available as an --expert feature in PGP? You can see this code in the latest version of GPG v2.2.40. The documentation doesn't just not say it's an export feature, but it says it's the default

GnuPG supports ECC since version 2.1 and creates ECC keypairs by default since version 2.3.
