FWIW, I noticed that someone recently asked about the status
of the ECC Brainpool curves on the Fedora Legal list:

https://lists.fedoraproject.org/archives/list/le...@lists.fedoraproject.org/thread/WUQNAB4EPWSJMMVECL2TZGKB5KIDESII/

With luck, a fresh review by the Red Hat legal folks will
result in those curves becoming accessible in the Fedora
libgcrypt packages.

Cheers,

Yes, the disabled Brainpool curves lead to the import problem.  I'll see
what we can do.  See https://dev.gnupg.org/T5162
