Then how is the client supposed to handle the data? Guessing?

Protos have all these.

Yes, super useful. Depends on how your application needs to use S-expressions. You could define DSLs for a very expressive and complex rules-engine with S-Expressions forming your rules. Now you can write your rules as text, pass it around and build rule evaluators of those expressions all on top of Ion.

It's interesting to have languages written for and in the same specification as your data.
