LGTM.
I wonder if it's good to also mention why Serializable is not a good idea?

Do you have an explanation? I'm not very familiar with Java coders.

I think it's a good addition. I wanted to say "as much as Nx" instead of "much larger", but I don't know how much larger. 2x, 10x, 100x?

the only reasons I can think of are:
1. Much larger data sizes when using SerializableCoder
2. Non-deterministing encoding when using SerializableCoder

Here's one example:
- https://blog.softwaremill.com/the-best-serialization-strategy-for-event-sourcing-9321c299632b
In this example, it seems ~10x, and also worse in performance.
In this blog post: https://devopedia.org/data-serialization they mention Oracle saying Java SErialization was a 'horrible mistake', and compare other serialization methods.
