Ofc not exactly like current 3RD party addon.
Why would the dev make a hard fight, then at the same time make a direct counter to its own design? It makes 0 sense.
The thing Blizzard shall do is to make “information” clearer in their design: colors scheme, spell effects, ability timers. etc.
It shall make information clearer for players, not doing things like auto marks, voice alert, warnings like “move away”,“stack up” shouted directly to your face as DBM.
