Comment (by kkmuffme):

 Btw I'd even go a step further (as a separate ticket/PR) and check that if
 `$wp_current_filter` isn't empty on shutdown, we should prevent the last
 hooks callback from running again in shutdown (in case that hook would be
 executed on shutdown), since calling exit (or throwing an error) in a
 shutdown function, will also exit any/all shutdown functions that would
 run after it - and since we already know that at this point in time, it's
 easy enough to prevent.

 The question is purely whether only this filter callback should be removed
 or if that filter is called again, we just return and stop WP execution
 (but not exit; to allow any other shutdown to run)
