Removing features from a programming language is almost impossible; it breaks backwards compatibility and so is a hard barrier to upgrading from the old version. Note the 12-year-and-counting struggle to adopt Python 3, or the fact that Perl 6 developers gave up completely trying to get people to upgrade from Perl 5 and just rebranded it as a new language instead.
C++ has opted to avoid those struggles by never removing features; you can disagree with that decision but it was done for good reasons.
