Is it still possible to collect email subscribers from users with JavaScript disabled?

Up until Ghost 2.0, it was possible to collect emails using an optin form that still functioned with JavaScript disabled.

I am working on implementing Ghost 3.0 members features (starting with just Ghost 2.0 level email subscribers) in my themes in a way that is accessible and works without JavaScript.

The subscribe form on http://demo.ghost.io does not seem to work without JavaScript, and I haven’t found any other examples that work with JS disabled.

Does anyone know whether this is still possible? I would greatly appreciate any help!

I’m guessing no, because submitting your email address sends a JSON request to the API, rather than a form submission
