Actually, I think only the Emergency Movement ability is tagged with the "can be repaired only at a SY" clause. You should always bring a few SY ships in your fleets anyways, as they can greatly extend their functionality. EB some repair stations to get tons of damage repaired instantly, or to make minor modifications to all the ships (such as removing Stealth/Scattering Armor if you come across a Religious enemy) far from your planets, etc.
