No, you should not unwrap unless you know it is safe to do so. You should also add a comment why it is safe to unwrap, if it is not obvious.

Many programmers are writing code for sunny weather only, with error handling being something you might add as an afterthought if your code starts to feel a little too brittle.

In my eyes error handling is just as important to do correctly as getting the core of the functionality done, because error handling is a core functionality of any program, especially if we speak of libraries others are meant to use.

Error handling is what differenciates engineering from coding.
