Hi Robin,
Thanks for bringing it up.
Could you directly get in touch with Fedora legal team?
We discussed a similar case for libgcrypt earlier, and the decision was to continue to not support brainpool curves.
https://lists.fedoraproject.org/archives/list/legal@lists.fedoraproject.org/thread/WUQNAB4EPWSJMMVECL2TZGKB5KIDESII/#WUQNAB4EPWSJMMVECL2TZGKB5KIDESII

I will close this bug as WONT FIX for now. Once we have a decision from the legal team, let us look into the next steps.
Hope this is fine for you.
Thank you.

Hi Sahana,

it looks like the ECC Brainpool curves can be included in Fedora now [1].

Thank you.

Richard Fontana confirmed Brainpool ECC is allowed for Fedora in this RHBZ [1].
