One that comes to mind is in conjunction with an error trap (output buffer hack 
to catch fatal errors and immediately notify an administrator). I could imagine 
using html_errors specifically because it would make it easier to parse the 
error from the output buffer.

Of course, in this case I see no reason why the error trap couldn't set 
html_errors at the same time as it sets display_errors and error_prepend_string.
