My theory is that they only did it for creatures they believed/knew NEEDED to be recognized as aliens, as least for Doctor Who. They probably made the Unfinity creatures aliens because they knew their creature types didn't matter. Giving the aliens the alien creature type in eoe restricts the type of art and non-standard sets they can be printed in. For example, if any of the insects see play in older formats and WotC decides they wanna reprint some, they'll be forced to give it the Eumidian/eoe aesthetic instead of giving it any new art with the Kraul or the Nantuko like how they've changed the artwork for other famous cards.
