When we click on 'Autocomplete' in the Ship Design window, do the components that are being automatically assigned to the ship depend on the mod, or is the feature hardcoded? Because I've just tried 'auto-completing' a small satellite, the first one we get , non-researched, chose the "Satellite" ship type, and got among others a Solar Sail assigned to it. The listed speed was still 0, but hey

Edit: Solar sails are also getting assigned to bases.
