I've done this a few times where I Accidentally breed the wrong dragon. So why can we cancel an unwanted nesting?

I support this! There have been many times where I've accidentally bred two dragons before or wished I could cancel it halfway though the incubation period because I've decided the pair might not make great hatchlings/I won't have enough lair space for them anyway. However, there would have to be some sort of trade off for this so you can't just cancel them all willy nilly.

Oh please this.

I've put dragons on nest with the wrong dragon more then I could count...

No support

You can preview the pair, and it has a confirmation that you actually want to breed the pair of dragons.

Support. While breeding the wrong dragons hasn't happened to me yet, I'd like the option to discard a nest if I ever do make that mistake in the future. I have a lot of dragons I have to intention of breeding and would be devastated if I accidentally put them on a nest.

Support (provided the cooldown remains).

I haven't bred the wrong dragons. Ever. I feel like it'd be pretty hard to do (except on mobile, where I'm such a butterfingers I don't even touch the nesting grounds).

I still want this because I do have this pair that I want to have just one hatchling. With this option... it'd be easy. Even if it would likely take forever. Because you know how you always get those 5-egg nests exactly when you don't want it.

Not to mention those every-now-and-again mistakes.
