Knowing the origin of the function is a huge benefit, but also imports create compile time dependency. In this case, it's not an issue, but when you're importing a lot of things across your codebase, it can become an issue.
I don't avoid import but I generally I strive to import one module where I'm going to be using many functions. I rarely bother with `only` unless it's absolutely necessary due to conflicts otherwise specifying `only` is a good indication I don't even need to import.
