The fact coal generation went down is irrelevant. Coal got down because domestic consumption dropped and Germany switched from net exporting 60TWh/y to being either neutral or net importer in last year.

Since the goal of energy transition is first and foremost decarbonization, if you close a low carbon source while keeping higher carbon sources, you can say that the worst polluter replaced the closed source

The structure of my comment is privileging coal because it has the worst emissions in the context of the ultimate decarbonization goal (among other nasty enviromental impacts from it). That's why it's coal that replaced nuclear and not renewables nor gas.
