Will GP electric drive gliders be certified to aerotow with the boom deployed and the motor turned off? (Boom extended in case of PT3. Aerotow to save the battery charge for later in the flight.)

Has this been done before? Any german motorized gliders "certified" with engine deployed and not running? I've never heard of such a thing. Yes a FES is probably safer for towing, but FES and boom motor are apples and oranges. I'm curious to know you question reasoning.

I've aero towed the ASH26E (EXP) with the engine running. 5000RPM worked best.
Up and not running would be silly. Similar to air brakes open.
Don't understand how a FES would be safer for towing. Wouldn't the ropy bit get stuck in the propellery thing?
