In addition to finetuning how race works, if there is one more "eyebrow raising" update that I want for the 2024 consolidation, it is that every class can express their archetype at level 1. (For example, that an Eldritch Knight has no magic at level 1 feels absurd to me. What were the high elves and githyanki doing for all of those years growing up training to be gishes?)
Perhaps, archetype at level 1 can be stealth-errataed by offering various feature swaps at level 1. The same kind of feature-swap options in Tashas that improve the Ranger, and so on, could appear in a future UA to swap in archetype features at level 1.
