@ian Ah, his argument is from the dev side, not the user side.
While I understand libraries can freak out, removing the alt attribute completely (versus <img alt> or <img alt="">) will cause most screen readers to announce the file name.
Oh, and is a WCAG SC 1.1.1 auto-fail.
But if he meant <img alt> versus <img alt="">, then no worries as they are exposed the same.
