Hi @JohnTortugo 
you don't need to open a backport JBS issue. It does no harm if you do that, but except for rare cases (if you need a CSR) it's done automatically by Skara.  But if you opened one Skara will pick it up automaticaly.
But please don't add a fix version, that is set automatically.  Currently, we are developing for 21.0.9. If you want to get your change to 21.0.10, you can withdraw and request approval again in two weeks.
