• Describe the issue
  The F-35 branch doesn't allow pushes because it was blocked when the package was retired and just closes the request as invalid (https://pagure.io/releng/fedora-scm-requests/issue/36475) because the branch exists. But on the unretire ticket it was stated to request branches this way (https://pagure.io/releng/issue/10279).

The push fails because the git is blocked, and I suspect it's also blocked in koji:

$ git push
Total 0 (delta 0), reused 0 (delta 0), pack-reused 0
remote: Branch refs/heads/f35 is unsupported
remote: Denied push for ref 'refs/heads/f35' for user 'pbrobinson'
remote: All changes have been rejected
To ssh://pkgs.fedoraproject.org/rpms/python-aenum
 ! [remote rejected] f35 -> f35 (pre-receive hook declined)
error: failed to push some refs to 'ssh://pkgs.fedoraproject.org/rpms/python-aenum'

The request-repo should check if the branch exists if it's blocked in git/koji and rather than just closing the ticket as invalid do the required bits on the bits to ensure the access works.
