AFAIK, #basicNew is a low-level essential method which should *never* be overridden by application methods, while #new offers a stable facade over #basicNew for applications.
Essentially, #basic* methods are calls to primitives in VM which reify basic objects of the object model like float, symbols etc. They are coupled closely with interpreter and object memory structures and functions. Application classes do not concern themselves with size and layout of such objects and use the facade methods like #new.
It is like the difference between a system call and runtime C library function. A C function like malloc maintains a stable interface to the app while its makes different system calls on different OS implementations.
