After I learned about the 'showing beacon path' option, I kinda feel like the 'dead end' path is now doesn't have any purpose in the game anymore and its existence now is, to me, just a reminder of a bad design.
... Or so I thought
There was this one time that at the beginning of the sector I got the mantis event that they will escape in the first fight and you get a weapon if you follow them and win the 2nd battle— They escaped into the 'dead end' path at the very end of the sector and the beacon leads to nowhere... I could almost heard the mantis shouting "HAHAHA! So long sucka!

" as they jumped away and "Oh, you scared now!? Come on, Fight us! HAHAHA

" as I had to put my responsibility as a captain of the the ship before my own personal feelings and begrudgingly ordered the ship to took on a different course in order to ensure the survival of the Federation...
It almost like the whole thing was planned! ... But then again, for many, many time, the 'blindfire' targeting system that the enemy use seem to results in some of the most complicated, subtle, clever, devious, and effective way to destroy you in the most humiliating way...
