Air combat superiority will do only if you're still beyond missile range at that point. Otherwise the other side also shoots back a long range missile at you, and it's likely to end in mutual destruction. And even if it's not, you revealed yourself, so better not be outnumbered. That reduces the usage in air combat.

This simply isn't true. Long range air to air missiles have to lock onto a radar return. The enemy might be aware that you've launched a missile at them, and that might tell them where you are, but it doesn't give them a missile lock on you in return. If your stealth is better than their detection, return fire becomes significantly less likely to be able to accurately target you before your missile hits.
