Hello,
I will keep it short, we have resolution for the BZ#1379484/1038683 as subject suggest p224 is permissible in Fedora now. As of now I have dropped the patch removing it from Fedora's golang. All active Fedora releases, f25 and rawhide(epel6 tbd) now have the golang with p224 re-enabled in build roots and updates are submitted in bodhi.
Please test and provide karma.

Thanks to all people involved in the reassessment,
