Yes.
Big problems with the exclusion zone:
1) It only appears at all for the current reference body. If there are multiple objects close together you can hit the exclusion/orbital cruise zone for one without being able to see it
2) It only appears depending on your trajectory, so if you're facing away from the centre of an object but still within the exclusion zone, it might only become visible too late to turn
3) It only appears depending on your speed, so if you're travelling slowly you can't actually tell if it's safe to speed up or if you're actually pointed into it
If it appeared in the same conditions as the planetary mapping blue spheres - solely dependent on the apparent angular size of the exclusion zone, and becoming visible when this exceeds a few degrees - it would be far more useful.
I reported it as a bug with a bunch of screenshots at
https://issues.frontierstore.net/issue-detail/660 if anyone wants to add confirmations to that before it expires.
