The star map screenshot looks very similar to star map in "Remnants of the Precursors" [1], which is a modernization of 1993 "Master of Orion" [2]. Convergent evolution, or was 1995 Stars! an homage/clone of Orion?
I can't speak for the authors' mindsets, but the Stars! map had pointwise movement rather than via strict stellar/planetary waypoints. When fleet interceptions can happen midcourse[1], there's not a whole lot of design room within the Win16 style.
[1] — If I remember correctly, there even was some special-case code for ship pursuit cycles.
