Don’t try this at home, but IndieWeb Custom Post Types now has to option to add a most basic “IndieWeb” Gutenberg block as well as add microformats to any theme that supports the Full-Site Editor. Also, the CPTs themselves (and any feed changes, and so on) have become entirely optional. The plugin also comes with the option to enable Webmention (but does not [yet] display webmentions on the front end).
