So I'll be able to use it in node if I use the experimental es modules?

not yet. This landed in V8 master, so it will be another couple months for that to land in Node

Isn’t that blocking main thread now?

Top-Level await won't block the main thread. It will block execution of parents until bindings are exported, but siblings will be able to execute independently.

To be completely fair, the first example would need to show how to deal with propagating errors, too. It's so cool you don't need to think about that anymore!
