I just received a new S4 here in Germany. When I turned it on, I immediately activated Download Modus. It shows Knox Void Warranty 0x00. So far, so good.
Now, I read through this thread and am not sure, if I understood it correctly.
1. Does the fact above mean that I cannot root/install a custom ROM (I would like to install Google Edition) or does this just mean that if I do so, there will be no warranty from Samsung any longer?
2. If it is still possible to install a Custom ROM (which is, what I assume), is it also possible to go back to the stock ROM (I know that this will not reset knox warranty void status, but I don't care) in case I want to sometime?
Many thanks in advance

As soon as you flash a GE ROM, your warranty is void anyways.
So you do not need to care about KNOX one bit.
I got my SGS4 in July, I used stock, GE, CM 10.2 and now PA. Why should I care about this at all when my warranty is gone anyways.
Additionally, I have an additional warranty from my carrier. If I brick my phone I get a new one anyways.
A little bit OT:
I am perfectly OK with Samsung's approach here. They need to have a good security feature to get it certified by companies for corporate phones and BYOD.
OTOH you can still just enter download mode and flash a recovery if you o not care about KNOX at all.
This is a much better approach then e.g. Asus' one. It took me weeks to unlock my Asus TF700T, because the Taiwanese Asus server did not know my device. When it worked I had to mess around with adb and command line tools like fastboot.
I prefer Samsung's approach, thank you. Some guys complaining about Samsung here are in for a nasty surprise when they encounter devices where you cannot just boot into download mode and fire up ODIN.
