I don't understand this argument, which I've also seen it used against C#, quite frequently. When a language offers new features, you're not forced to use them. You generally don't even need to learn them if you don't want. I do think some restrictions in languages can be highly beneficial, like strong typing, but the difference is that in a weakly typed language that 'feature' is forced upon you, whereas random new feature in C++ or C# is near to always backwards compatible and opt-in only.

For instance, to take a dated example - consider move semantics in C++. If you never used it anywhere at all, you'd have 0 problems. But once you do, you get lots of neat things for free. And for these sort of features, I see no reason to ever oppose their endless introduction unless such starts to imperil the integrity/performance of the compiler, but that clearly is not happening.
