Is It Okay to Not Worry About Sync vs Async in Effect?

One wild part of the experience of using Effect is I found myself no longer really needing to think about which functions are synchronous and which ones are asynchronous. If I want something, i just yield* it. before this any async function would kinda “polute” all funcs that consume it.

I like it and it feels magical but is it really OK not to worry about this? am i missing something?
