To your second bullet point, then this could've meant getting a dialogue branch for AA disliking Half-Mindflayer Tav, but it wasn't included.
Why? For people to complain about it again, so that Larian deletes it later? Like I said, AA already has his own dialogues about Spawn Tav. He also has much more explicit sex scene with them.

What I'm saying though, is that his good route is clunkily written in not trusting the viewer to figure things out themselves, so they just beat you over the head with it, when it'd feel much more natural if Astarion didn't look straight into the camera and went "Oh yeah I broke the cycle of abuse and stuff", which I think is obvious to anyone who is willing to engage with the story, so it feels goofy when he makes it clear like that was necessary.
But this is about the quality of writing, it has nothing to do with how much attention was paid to Spawn vs Ascended. It's a completely different topic.

To your third, Tav running after Spawn is much more complicated to the flow of the ending scene than the kisses.
It could have been resolved in a different ways, also, Tav is silent, so you don't even need to record voiced lines for them. I think it was completely doable - to show that Tav at least cares - as much as fixing AA kissing animations.
