Not just maneuvearable, but actively maneuverable, aka able to sense some type of input inside the cone of visibly superheated air around it. This is different than an ICBM RV drifting around with RCS before re-entry or a cruise missile idling about before it's accelerated to attack speed.
Unrelated but that's also why any talk of stealth with hypersonic is stupid; everything around the projectile is going to give off more of a signature than the projectile itself

For ICBMs these are called MARV warheads and they were first demonstrated in the early 1980s, and every major power has had them, though many don't have any operational now.
I keep reading this comment on HN. It's like saying "What's the deal with Chuck Yaeger breaking the sound barrier, we've had supersonic bullets that do that for a long time". There is zero overlap between the two.
Maneuverable reentry vehicles can wobble around a bit while falling, whereas the point of hypersonic weapons is maneuverability for a significant part of the trajectory.
