Comment (by knutsp):

 In case `WP_DEVELOPMENT_MODE` is defined as a legal value and
 `WP_ENVIRONMENT_TYPE` is undefined `WP_ENVIRONMENT_TYPE` should be defined
 to 'development'.

 `WP_DEBUG` may explicitly be defined false, and still
 `WP_ENVIRONMENT_TYPE` could be 'development' and `WP_DEVELOPMENT_MODE`
 could be either undefined or set to false or an empty value. Debugging is
 not the same as developing, all the time, and vice versa.

 What is the use case `wp_i[n|s]_development_mode()` to check for any mode?
 The environment and `WP_DEBUG` should be sufficient when it's about
 reporting, logging or checking that may slow down the site. The mode is
 primarily about caching and avoiding internal behviour that makes certain
 kinds of development harder, slower or unpredictable. But if one still
 insist some may need this, `if ( wp_get_development_mode() ) {}` will work
 without explicit casting to boolean.
