I took a pretty hard look at them and judged them alongside the weakness of planetary defenses. Basically the weakness of PJI reduces the ability to create choke points at all.
I modded it so that they have antimatter, and will auto-use the ability (or you can choose to disable and use yourself) and turn off phase jumping entirely for 30 seconds (60 seconds if full of antimatter). This way, if you choose not to scout, be prepared to possibly get rocked.
I should mention my mod also plays at double speed, so 60 seconds is a very long time. Enough to probably kill a capship if they ran into a fleet at the planet without scouting.
If you really want to get your jump enabled faster, you need to destroy the module.
They also are 2x the cost of all resources and take 6 tactical slots.
