Why would ever block a thread if you can do without blocking it? Threads are extremely expensive resource regardless of what kind of app your are writing (frontend of backend). Of course, there are some apps where this just does not matter (e.g. they don't have much of concurrency or asynchrony) , but if you actually in a domain where you need coroutines, then it makes sense to exploit them to their full power.
