Thank you for taking the time to test, Ingo.

The use of passphrase may be responsible.
I tested it on Fedora 36 and FreeBSD 13.1.
Fedora uses GnuPG 2.3.7 and I built the git master branch on FreeBSD.

$ gpg --version
gpg (GnuPG) 2.3.8-unknown
libgcrypt 1.10.1

In both cases, I get the warning when importing a cv25519 key.
Likewise, when no passphrase is used, there is no warning message.

I haven't tried upgrading libgcrypt to something current; perhaps it could help.
