Not from below. From above. IMINT countermeasure, to make countries with imaging satellites take longer to notice you flying silent over water into their airspace (presuming you've already got MASINT stealth covered, and are moving onto higher-hanging fruit.) Gives aircraft the same long-distance stealth advantage a sub has: they don't see you coming until you're there.

(Admittedly, I was being a bit silly with the missile use-case.)

Being able to retint your visible spectrum view from 10,000ft and above would be useful, I agree.

I occasionally see referrals in flow text to a Chinese claim they invented "holographic quantum" radar and can see all current stealth low echo aircraft and subs. I suspect it's bullshit but in war, if stealth was a purturbation, and deep water subs a more historical perturbation toward MAD and now, this is another perturbation much as drones have altered the symmetry for tank and mechanised ground warfare..
