I don't think that it ever will as that requires reigning in spellcasters and restricting players' toys.It's something I believe D&D is beyond due exploring. The lowest you really get is Dark Sun and that hasn't made it to 5th yet. And even Dark Sun isn't that narrow
I would definitely be curious how D&D would look if 5th level spells was the new max cap for full casters, but that's something that 3pp would explore rather than WotC. So not quite as restricted as say Adventures in Middle Earth, but also not as high as D&D's default range.
