Yeah, it would've been far better, that's for sure.
I know I've said this before, but it wouldn't be so bad if they had at least been mentioned or whatever before, but they weren't, and anyone who tries to say otherwise is just trying to lie to themselves.
And I think that they could've done it in a similar way to how they handled that Sludge or whatever dragon who said
They didn't need to go full Fresh Prince of Bel Air, in that the parent had to be a huge scumbag or anything, but just that made the mistake to not keep caring for her.
And heck, maybe they could've gone further with it, like having Snap Shutter and Mane Allgood have been happy expecting parents and all, but one of them sadly died shortly after Scootaloo's birth, and the remaining parent just wasn't in the right frame of mind to take care of her. So they chose to leave Scootaloo at the Ponyville orphanage and they could've regretted doing that, but understood it was for the best at the time.
They could've gone even further and had them not desire to try to force themselves into her life in a forced relationship or anything like that, but just let her know that if nothing else, they'd be there for her if she truly needed them.
They could've actually made use sympathize with them and all that without trying to act like they've been around the whole time, which is just stupid and lazy writing.
