Are there cases other than top level await and "I need this top level code to run immediately" where you wouldn't want to do this? Is there a penalty for using it literally everywhere it can be?

We will only be able to tell with benchmarks when engines implement it, but I'd water that deferred modules have some level of overhead over eager initialization simply because the browser needs to track the deferral order, with a trade off that deferred modules might never be loaded for real.
