Current frameworks might be broken if the way fatal errors work is changed. That would be a BC break. See e.g. http://stackoverflow.com/questions/16284235/zend-framework-error-page-for-php-fatal-errors/16284260#16284260 (This is not a vote for or against this proposal; I'm just answering the immediate parent here.)
