Comment:

 I think this is still worth doing. It's something that both core and
 plugins have to work around. There are CPTs in core where I'm aware of
 KSES potentially corrupting valid `post_content`:

 1. `custom_css` which contains CSS (for which KSES can corrupt valid CSS,
 as seen in #64418).
 1. `customize_changeset` which contains JSON (which has a workaround to
 bypass KSES).
 1. `wp_global_styles` which contains JSON (which has no KSES override, but
 Additional CSS appears to be disabled if the user can't do
 `unfiltered_html`).

 See [ticket:64418#comment:16].
