As it relates to question of the thread -- the inclusion of lore in the core rulebooks for D&D 2024 -- I know the ship has sailed, but I still think of D&D as a game with a strong implied setting but meant for the GM to create their own setting. I feel like 5E has consistently gotten away from that and the included lore of the 2024 PHB and DMG makes it harder than every to just ignore it (similar to how Golarion has infused the PF2E Remaster Books more than the previous books). My preference, then, is for a D&D with a strong flavor, but no established Truths.
Also, I think Lore eats too many words that can either be excised entirely, or used to actually support play.
