I think the 300th episode of Thinking Elixir w/ José as the guest included a discussion on that point exactly, and if I remember correctly it was a "it depends", but I took away "probably not worth adding more labor into putting it in if you haven't already".

I haven't had it catch something before the compiler in a while. I still use typespecs for their documentation benefit, though I've been using `defguard` w/ `is_struct/2` and complex guards a lot more in recent years.
