Does this need a #[derive(Serialize, Deserialize)]? I don't know, and maybe we wont until we start to use it? :)

We cannot easily. Serde requires the GAT to be serialize/deserialize unless we tell it otherwise.

Gotcha. And .. no particular reason to want to serialize / deserialize these, outside perhaps of interest in some DD-based persistence? I guess I forget why the derive(Abomonation) was there in the first place, and perhaps there was no reason anymore?

Same as above; removing a derived Abomonation without introducing Serialize, Deserialize. Idk the consequences.

All looks good to me, except a few moments where we lost an Abomonation derive and did not replace it with a Serialize, Deserialize derive. That might be fine (perhaps it was unused?), but I wanted to flag them in case they are known oopsies.
