It's kind of tough, nobody missed out, they took everyone who qualified (by their standards), they just didn't take all the discretionary spots they had available.
That being said, Blocksidge had the World aquatics A time so she could have swim given there are no other distance swimmers (of either gender), in the squad. I would have taken Hanlon so that every stroke 100 has two swimmers per gender. She has the A time in the 200 so she could swim that too.
I just noticed there was European Judo Championships Open in 2023 with only men's 73 and women's 57 events. What was the point of that event? What was the difference with normal European Championships?
