To be completely accurate, it was rejected *for PHP 7*. PHP 7 was announced suddenly and rushed through. I think a BC break of this magnitude in PHP 7 would be incredibly painful *because of the timetable*. Whereas if we decide now that in PHP 8 all identifiers will be case sensitive that's a different story because of the timeline. Knowing years in advance that something will happen gives you ample time to migrate (like we are doing with PHP 4 constructors in the PHP 7 series; they are deprecated and support will be removed in PHP 8).
