https://pkg.go.dev/errors#Is and https://pkg.go.dev/fmt#Errorf clearly state that there is a way to match these errors if the package exposes the values, which the stdlib does.

Which only works when the error itself doesn't contain any information.

It's better than nothing, of course.

Ah okay, it seems to work because errors are pointers, and errors.Is just checks for equality.
