Please see the status listed right below the task title.

Is this issue still open?

No rush at all, just a suggestion. Please take your time :)

I wanted to wait a bit in case there is some caching involved (don't know), but removal is already scheduled.

@hgzh, now you should remove that code from dewiki MediaWiki:Common.css.

Thanks!

Done

[mediawiki/extensions/Collection@master] Hide disabled download box from Special:Book

https://gerrit.wikimedia.org/r/1007673

Cannot reproduce with the current PDF download system. The PDF file downloaded instead doesn't show the language list at all, which is reasonable behavior for a PDF since it would be links that probably don't work in a printed context.
