Changes between Initial Version and Version 1 of Ticket #46743, comment 11

initial	v1
1	1	A method involving the use of `add_theme_support()` is doable but I don't like the idea of having to define both the hook in the template and a support string in my setup functions. It seems redundant to need both.
2	2
3		Could we instead add a support method late (directly inside the `wp_body_open` hook) If a theme includes the hook in their template then it auto-adds the support. This would mean that plugin developers would need to do late detection.
