iirc only maintainer can promote. Even anyone can upload to devel.
But it is possible to get maintainership pretty easy.

Let us wait a bit (quarantine time) and then let us see if halftux or me can promote it.

Furthermore I need to (re)install that package from devel and check ...
Checked!

QA already ended, so halftux plese check if you may promote.
