The easiest way is to not push out any patch-queue/* branches at all. They can be recreated by any team member easily by using

  gbp pq import --force

The patch-queue branch can also be re-created when pulling (this will additionally drop your current patch-queue branch and recreate it from debian/patches):

  gbp pull --redo-pq

Note that you can push out patch-queue branches. Other team members must just be aware that branches in the patch-queue/ namespace are being rebased frequently and therefore cause non fast-forward updates.
