IMHO it already IS safe. In PHP 4 the "constructor" was a method thad had the same name as the class. But now it is a class that has always the same name and is always preceded with two underscores. There is no way to "accidentaly" call that method. You have to explicitly call "__construct" to "break" things. If developers "want" to break something they will find a way. Protecting "__construct" will not stop them from doing so. But it will stop the rest of us do legitimate things.
