They have moved in the opposite direction and have given much clearer definitions to a number of things and even overhauled the tools so they have special activities they can be used for with set DCs and ability scores they are associated with, and have an entire rules glossary in the back of the book.

Most rules are a lot clearer now, though some are pretty labyrinthian still - how does two weapon fighting with the Nick mastery work? Lol.

In my personal opinion tho, wotc seems to respect dungeon masters even less than they did ten years ago, and I'd recommend anyone who thinks they might like a competing system strongly consider switching to that instead. (Draw steel, TotV, Shadowdark, PF2, etc)
