Is publishing to web working and fully supported?

Iced Web is no longer maintained.

But if you want to run your iced app in a browser you can still do that. It uses a html canvas to display your app.
Here is a link to a guide the covers how to do that Wasm - Unofficial Iced Guide (for transparancy I am the author).
