Comment:

 I did not think the deprecation notice was appropriate when the problem is
 in Core, but it does tell theme authors how they might ''work around''
 that problem.

 I tried adding block theme markup to the theme-compat files and attached
 it here in case someone would like to continue working on that concept. It
 seems less and less like a viable solution, even temporary.
 - The styles and scripts are still wrong, yet disallowing the separate
 assets option helped some.
 - The pages lack a skip to content link.
 - At first, the title and viewport meta tags were not included with
 `wp_head`. Updating the `_wp_render_title_tag` function and removing its
 Gutenberg replacement might help, regardless of whether the other changes
 are made.

 We may need to prioritize the refactoring tickets in the next release
 cycle (#31928 and #33500).
