A friend of mine has a trans gf from Germany so he explained this quite nicely to me today. There are still two relatively peripheral issues. One is that surnames can't be changed, which is a problem for anyone from a language with gender-marked surnames (e.g. Russian, Ukrainian, Czech). It's not an acceptable situation neither with regards to gender nor to grammar (masculine name + feminine surname is just... wrong). The other is that apparently when transitioning you have to change your name, which shouldn't be necessary for those with gender neutral names that they'd prefer to keep.

I think you can keep it now if it's gender neutral! But I still think it shouldn't be any of their business to judge whether your name matches your gender identity, it's pretty personal.
Right, that's why I listed several languages where the surname is gendered, and people who are native to those languages (including their naming conventions) also live in Germany. Especially today, considering the exodus of Ukrainians.
For example, the current president of Ukraine is called Zelensky. His wife, who took up his surname, is called Zelenska. Or, there's Putin, and his mother/sister/wife/daughter have or would have the surname Putina. The -y and "null" endings are masculine, -a is feminine.
Surnames can always be changed if there's an important reason. You could argue that this would be the case if you have a gendered surname. Worst case someone has to sue to get precedent on this.
