Seems like a huge disadvantage for nuclear?
Also the fact that nuclear works best when outputting constant amounts of energy doesn't really seem to be an advantage - https://www.euractiv.com/section/electricity/news/german-nuc... ?
These problems will still exist for any power source (planned outages and following demand). Nuclear is no worse than wind power at these things, so why does it matter that it doesn't perfectly solve these issues as well?
When there's a planned outage, you can schedule other sources to scale up as needed. Following demand is hard no matter where the power comes from, but for wind it's even harder as you can control neither supply nor demand.
There's no ultimate, perfect solution. But I see Nuclear as a good option to be the major strength of our power systems.

Consumption naturally spikes, when you add the natural volatility of wind power, you have greatly increased need for quick adjustment. Germany is using practically everything else than wind and solar to adjust. They also sometimes have to sell power with negative price. As a result even nuclear gets pushed into a role it's poorly suited to.
