Visited yesterday.
The "public charging" sign has been removed. The Keba charger has also been replaced with a go-e. The green parking space is still there.
I tried looking at Google Street View for additional data points, but all images are quite old. The images in Bahnhofstrasse are from 2014, before any charger was installed. The images from Güterstrasse are from November 2022, the green parking space is there and I think the station is already Keba, but we can't properly see it and whether there's the public sign.
