Canards and stealth. . .

From here:

Of course some will immediately jump on the “see, canards are totally compatible with stealth” bandwagon, BUT consider that Northrop didn’t want it when they didn’t HAVE to have it. They only added it to deal with the low speed carrier requirement. Same with swing-wings (someone mentioned those). They aren’t great for stealth either. Why? Edge alignment. Do you align it for slow speed or high speed, or somewhere in between? Also it introduces more seams and all your high lift devices would introduce more gaps to deal with. The F-23 NATF would have (apparently) used a canard whilst the F-22 NATF would have used a swing-wing. Again, I stress (not that it’ll even register to some) that if canards or swing-wings were a superior solution for stealth the USAF versions of the ATFs would have had them. Neither did.
