[TYPO3-core] TYPO3_MODE "die" in Configurations/TCA

[Bernhard Kraft]

Hi !

I was wondering whether the snippet
---------------------------------
if (!defined('TYPO3_MODE')) {
         die('Access denied.');
}
---------------------------------

Should get added to any new .php files like for example those in 
Configurations/TCA/[Overrides]/

Are they deprecated?


geetings,
