After all, I assume the forts are placed at their current range for a reason. But it might not be a good idea to totally rely on the platforms with an opponent who is stealthier than yourself. We all agree that proximity kills can ruin a sea of platforms.
Sharks destroying a sea of platforms? Wait! What?
Actually you probably wouldn't want to move the forts out much.
They should be far enough back from emergence lanes to be safe from energy mount fire (which is all a hostile transit can use until clearing the lane) - so at least 500,000 km back. But you don't want even the outermost shell of forts too close to the small hyper limit around the Junction -- which is "less than a million kilometers" [OBS].
Now staying out of energy range of a terminus's arrival lane means that you'd technical be within energy range of someone arriving exactly on the hyper limit. (Although you may be able to play games with geometry and utilize the RZ and some of its lobes that extend the unsafe emergence areas to find fully safe zones for some outer forts; but the text is clear there are parts of a junctions where only the hyper limit, and not the RZ, is in play)
Still, given the difficult hyper conditions around a wormhole and the dangers of even a small overshoot, the chances of someone emerging quite that close are
very low. (with not even 1,000,000 km radius of hyper limit, its out 'safer' 'softer' zone is very thin. Its bad enough if you (attempt to) emerge long into that and bounce off the Alpha wall and remain in hyper -- but hit the inner 'harder' zone within the hyper limit and you don't bounce; you splatter).
However, even assuming an enemy will leave themselves some rational safety margin, you still want even your outermost forts tucked in closely enough to make it difficult for an enemy to pop out of hyper within energy range.
Since your inner forts would already (if only just) be far enough back to be safe from hostile transits there's no reason to move them still further and make your defenses more vulnerable to hostile attacks from hyper.
