Last time you needed to, sure. The problem is that if you find out how to do dynamic memory allocation, there will be tons of resources pointing at new/delete. Parts of the language that all the experts agree are terrible are just sitting there, poking out behind a shiny facade, waiting to scratch the unwary.
How is that not the case for any language that lets experts get at the gory details what is the alternative?
Even in languages like Ruby this problem exists. Superficially, Ruby has a decent garbage collector and you never need to dereference a pointer. In practice as soon as it gets slow you hit an optimization stopping point and need to write an extension in C. Then you have all this mess again except with all the baggage another whole language brings to the table and none of the sheltering of a type system.
At some point you just have trust software devs to use the tools.
