Here's what I personally think:
Travel times in hyperspace are quite OK, especially for those who are not leaving the bubble very often.
Worse case is about supercruise, travel times here can be rally long (and the worse thing is that there is not much to do during these flights), but i think there is quite easy way to change it - not to much of course, to keep the feeling of distances.
FSD seems to be quite old technology - 10 years on the market now, and maybe Sirius Corp is already just working on FSD 2.0 in whitch acceleration and deceleration are better along with lower gravitational influence from celestial bodies to fsd effectiveness and maybe higher top speed in supercruise(all 4 solutions together or just some of them). This, done properly, wont affect short travels that much but can be great solution for long distances.
Probably this doesnt require any major changes in game mechanics or hours of development - just to change some numbers in
some algorithms.
This can be nicely fitted into LORE, because one of the attendants of the gallactic summit, hosted by Sirius, was Aegis delegation, and they as we all know, are responsible for counter-thargoid science.
How I see it, is that "Sirius FSD Development team" is anouncing new "FSD possibilities" after establishing new research contact (related to Aegis) during the Gallactic Summit.
Maby the case is, just to organize some CGs to deliver goods or wake scans for further development of new FSD??? After few rounds of different CGs(probably the fastest ever completed

, there may be possibility to upgrade software and hardware of FSD in any outfitting or shipyard facility.
If this kind of changes somehow will break the game in any way, this can be simply turned back to previous state, and again can be fitted to narrative part of game - Sirius anouncing stepping back to previous FSD version because of safety issues.
What you all think about it?
