Yes, I think so.
Yet another reason to always rely on the allocator is that the user
can supply his own allocator with special error reporting method (e.g.
by throwing an application-specific exception instead of bad_alloc).
The application may be expecting that the container will always report
memory allocation errors in this special way.
