Half-ass way of doing it could simply be blocking certain areas of the derelict from teleportation, force them to board it from non-loot areas and load it with fun little hostiles near the good loot. Make them need to work for their loot whilst not 'discarding' the possibility of visiting it via teleportation entirely so it isn't relegated to being a place you only come across when going on space adventures or drifting off when you forget your jetpack stabilization as a nuke op.
The derelict, whilst underused and mainly abused, makes for a wonderful playground for (group) antagonists. It'd be disappointing to see it made further irrelevant.
