Germany has weird history of energy politics. 20 years oil heating was bad one. Gas heating was the good one. Now gas heating is bad one and heat pump with renewables is good one. After 20 years heat pumps will be evil, because imported from China or another silly reason.

My recommendation for German government: make electricity cheap and nobody will think twice installing heat pumps or buying electric vehicles. Current price 0.3-0.5€/kWh depending on location what is insane.
