 > how strongly do you feel about this? You're the 6.3 tech lead, so it's
 your call.

 No strong feeling at all, just trying to brainstorm :)

 > We can always add more supported development mode values

 I'll be a bit worried about changing it much though. As far as I see the
 last thing that can be added would be to return when a development mode is
 set, regardless of which particular flavor.

 > If there is a real use-case where it becomes useful to check for any
 development mode

 Yes, there are few although I couldn't get the time to test and implement
 them. One is to change `_doing_it_wrong()` behavior (or the new proposed
 function that would replace it) depending on whether dev. mode is set.
 Thinking it may even throw a fatal error in some cases on a particularly
 "wrong" things.

 Another is to reexamine all uses of `WP_DEBUG`, maybe make some of them
 conditional on dev. mode, and maybe make some throw more severe
 errors/warnings.

 > I'd propose that the default behavior for this function if no explicit
 mode is passed (i.e. $mode = null) would be to return true if
 wp_get_development_mode() returns any valid value rather than adding an
 explicit "any"

 Yep, I'm with @joemcgill here. Thinking that would be best. Thanks for the
 suggestion.
