[Any space faring] What is the least weaponizable FTL system?

Many settings like Star Wars feature ships with shields and armor that can take an incredible beating but they should be destroyed by high speed projectiles that should be quite doable considering how inexpensive a FTL missile should be compared to a capital ship.

Hyperspace is actually not especially weaponizable, considering its easily countered by a simple interdiction system that is already installed on any ship that would actually be worth using such a weapon on.

In the Halo series the Prophet of Regret initiates a Slipspace jump while still in Earth's atmosphere, causing a huge amount of damage to the city of New Mombossa and scattering the UNSC ground forces. And this was (mostly) on accident, he just wanted to gtfo in a hurry and didn't bother to fly away first. Didn't really seem to hurt the ship any either. Slipspace bombs would be extremely effective, albeit expensive.
