Unfortunately, I find the game frustratingly slow on 1x hyperlanes and do not want to play it on that setting even in the name of science
I don't like slowboating across systems between hyperlane nodes in the first place, and I like it even less when the hyperlanes form a twisty maze of little passages, all different. Part of the reason I dislike it is that it makes hyperdrive upgrades a waste of alloys and reactor power, because travel times are absolutely dominated by sublight speed, especially once you start putting battleships in fleets. The only FTL techs worth getting for themselves are Jump Drive and Psi Jump Drive.
If sublight speeds were, I dunno, five times faster, I might feel enough differently about that to try playing the game on 1x hyperlanes, but official statements suggest feedback from modded games is generally not of interest.
