Yes, duplication isn't good and we should avoid adding new duplication
without a good reason.

However breaking compatibility isn't good either. Adding breaks not only
invalidates code but also tutorials, books, etc. which might confuse
readers more (while I admit, that a book teaching "var" might be
questionable in other ways, too)

        Quick Googling brings this tutorial, which first teaches "var"
        to get started and then changes to public/private/protected in a
        later step:

One could argue those were other times - I doubt anybody maintains a
single code base for both PHP 4 and PHP 7. While in early PHP 5 times it
had been common that people tried to produce code working on PHP 4 and
PHP 5 without notices.
