It makes it less serious in the north where shortage of electricity would mean freezing indoor temperatures. Heat pumps have reduced the amount of electricity needed (compared to direct electric heating) for heating a house and thus the amount of imports/storage needed. Also, if the heat pumps are a part of a district heating system, a heat storage solution can be included in the system.

In a country where heating isn't yet electrified, it's a way to reduce fossil fuel use and carbon emissions (the ultimate goal) without necessarily reducing the fossil electricity production. So even if it doesn't solve Dunkelflaute alone, it's a part of solving the climate and energy crises.

Germany is complicated, because they mostly use gas for heating, not electricity. So switching to heatpumps will require more generation. And for now this means new natural gas plants.

This is not _too_ bad in itself, using gas for generation and then powering heat pumps is more efficient than burning gas for heating. But the capital requirements for new power plants will cement Germany's dependence on fossil fuels for at least another 2 decades.

It's a mess.
