I don't think so, not as I understood
@Charlaquin anyway.
A perfect example (IMO) are prestige classes. A prestige class is a decision point as I see it. Getting the requirements means you have to establish a path to become that. In 5E, once your subclass is chosen (unless you MC) you have no options.
Now, that being said, there is a difference between decisions on your character's progress and just getting so many features and options thrown on top of each other leads to the the analysis-paralysis I mentioned. It happens
in game when players can't decide what to do, not so much during leveling, etc.
As for point 1, things like prestige classes impact PC development
during the adventure as those requirements are met (sometimes, anyway). Otherwise, there probably isn't a
huge difference between them as you suggest.
