That's quite an unexpected flux of posts. Cool.
I suppose the most "modern" and at the same time reasonable and universally-appealing decision would be to make waypoint usage a difficulty setting? Looking at how Pathfinder: Kingmaker handled it (difficulty adjustments), I don't see why a player shouldn't be able to customize their BG3 experience just as finely. Unless Larian stick to the rigid "Classic-Tacticican-Honour" selection again, there could be a lot of features that one can just enable if they feel like it to make their playthrough more or less "hardcore" (fast travel limitations, seeing check DCs, "helping" action only stabilizing downed characters instead of outright reviving them, and so on).
