Motivation

Refs #2038, #2268 (comment)

Doesn't fix it because you still need to replace kebab-case to snake_case

Solution

From tests I wrote when adding ethlive I've found out that the last serialize parameter is the one which is used when doing to_string. In this PR you're promoting the first one, which will break a lot of downstream.

Does this supersede #2268?

Yes. I don't consider it breaking since this is only changes the Display/ToString implementation and previous implementations can parse this "new" one because it was aliased. I also think it wasn't intended in the first place that the last item in the list is the selected one for Display.

Does this supersede #2268?

No
