One comment regarding chaos warp. I completely understand what you mean and that device wouldn't affect the warp proper but once that extra dimensional energy interacts with real space, its treated like any other dimension etc. 

Simple version, anything that effects the properties of real space, be it any dimensions or"realspace" ftl will not function. With that said, hau use waygates pretty often so seeing as the field would effect that travel as well, those gates are usually placed far from a population center and possess their own hammer systems. 

These jammers will have to be deactivated long enough to send a ship through then reactivated, a process that can take only seconds. And please know that those waygates are never weakly defended , so magically slipping forces in will meet resistance

Pretty much a no matter who you are, you can't just teleport, wormhole, dimension/chaos rift or fly at or above faster than light speed when in the effective range of an active device. Fair?
