Even if I'm not a maintainer anymore, since I was the one who opened this and assigned you, any update on this @Asartea?

This has unfortunately fallen a bit by the wayside for me for now, and I don't know when I'll have time; feel free to unassign me and assign it to somebody else

Had every belief in you :P
