This is something I'd like to work on as well.
I have to re-learn serde because it's been a long time I haven't used it. Now that it has reached 1.0 this should indeed be a good time.

Again, prost's config allows you to add type attributes. That seems like it would solve this, no? They recommend you add the serde attributes to the generated structs and it seems like it would just work.

This is a good idea!
