I am also surprised that I haven't read about this in German news before. I am following the news. If Trump would have signed an executive order with a similar content affecting US citizen, German media would probably report about this multiple days long with many articles.

I was looking in Google news for other reports about this, but only found an article from Berliner Zeitung published 5 hours after this article from Frankfurter Rundschau.

I am worried about what other information which could be important to me, the news did not report on.

As far as I understood the law the article from FR is correct: https://www.gesetze-im-internet.de/wehrpflg/__3.html
