not OP, but my current solution is to have a link which says "click to show email", with javascript handler that changes that link's href (and text) to email address, which is somehow computed. For example, by taking page URL and performing some regexp on it. It both avoids storing email in page source in plain text and requires human interaction, so feels good enough.

Another way I've seen elsewhere is to use a human-language explanation of how to build email address, something like this: "To get my email address, combine my first name (John) with my birth year (2000), separated by dash (-), and add email provider (@gmail.com)".
