To the topic - The existence of Dhampir as a suggested racial lineage as of Van Richten's Guide would, indeed, suit Astarion far better in terms of his capabilities, than being a spawn. Dhampir still actually retain their capacity for empathy and emotion (spawn do not), they have most of the same weaknesses and vulnerabilities that any other playable-race mortal creature does, but they have a few special perks - such as good darkvision, faster running speed, and a bite attack. This all sounds far more like the Astarion we have, than a spawn does. A dhampir would, in fact, die if you stabbed him in the heart with a long pointy object (regardless of the material it's made of), just the same as any other elf, human or dwarf would (this is not true for spawns), so that fits Atarion as well.
To continue to call Astarion a spawn means they have to run the argument that having the tadpole has, quite literally, stripped Astarion of nearly every single strength and benefit that he ever has as a vampire spawn, and that it has drastically reduced both his capabilities as a combatant, and also his survivability; it's functionally taken everything from him, with the exception of a very infrequent access to one fraction of his old powers (a weak bite)... and yet Astarion goes on about all the benefits it's granted him, and never once bemoans being unable to do lots of things that he could do before (and, let's be honest here: Astarion would definitely complain about not being able to do things that he once could, that's exactly his personality and behaviour type).
One issue with making the switch, of course, is that Dhampir aren't beholden to a master in the first place, so they'd need to really rework his personal story.
