Thats pretty cool!

To say this though, I prefer the file extensions bit, e.g. `.client.ts` and `.server.ts` over directives. Directives aren't super discoverable at a glance, and I think will lend themselves to a lot more headache in terms of engineering practice.

I realize its better for compilers probably, but it hinders DX for large applications IMO.

Initially we'd proposed just dropping `.client.` and keeping `.server.`. This area overall is still being worked out, and the two options aren't necessarily mutually exclusive.

That's good feedback. The directive approach relies much less on initial discoverability and tedious work which enables it, like naming each and every JS module a certain way up front. Instead, it relies on error handling and developer response/correction. I'm definitely curious to see whether that tradeoff is worthwhile.

I know Typescript now has a `moduleSuffixes`[0] option that may be be a reference point for making this easier. I am imagining you want to do this due to compiler conditions for build tooling no?

This makes it "transparent" to the developer but retains the file naming approach, best of both worlds?
