So it is pretty much a worst case already... I have some friends who might become Members of the Bundestag because of this, but even they are kind of irritated by that and know that nobody they will be talking to about their new seat will be happy about it.
The linked site lists a (more realistic) scenario already, where the number of seats comes out to more than 900. How did you end up at your 897 seat upper bound?
(Berlin's pirate party once won a surprisingly high share in the state parliament but wasn't able to fill all seats, because they were polling way lower when compiling their list.)
That's not correct. They had 15 candidates and won 15 seats.
For all the nitty-gritty details check paragraph 4.5 on page 67 of the official election results [1].

If the Bundestag becomes as massive as predicted (800+), the CDU and AfD lists are too short.
(I know that lots of politicians never or rarely show up to parliament anyway, but I think the idea is that they have a fixed seat such that it becomes clear which segment of the parliament is physically taken up by which party)
Fill in the visitor's balcony, I guess.
What's the other option, fill in the aisles? Given the frequency of terrorist attacks in Europe, preserving the ability of lawmakers to quickly leave a room seems more important than the feelings of journalists.
It's definitely a crowded house, and much more of a temporary arrangement (it looks like they had to take out most of the desks and swivel chairs)!
