i find passing through slipstreams when not aligned with my destination rather annoying, since autopilot handles it wierd, and i got to use eburn. Even if it doesnt make much sense, could "moving slow" allow you to pass through? Mostly QoL perspective
First I thought the same thing, but now with 10 hours in the new update, it looks a bit different:
A "you have to slow down"-obstacle already exists with the hyperstorms. Changing the slipstreams that way, would make hyperspace-travel a bit more boring again.
In it's current state it surely is a more difficult obstacle, but because of that it gives you a different and interesting challenge, with several ways to tackle it:
1. Using eburn, as you mentioned it.
2. Using an S-turn to get a bit of it's speedboost and passing it.
3. Checking for a system in it's way, because there are breaks in the slipstream and you can pass it without any problem.
