Not obscure, just a religious issue. Somehow in the creation of the C++ standard the definition of void * got changed from "generic pointer" to something else I've been unable to fathom. That definition, whatever it is, justifies forbidding implicit casts from void * to anything else. Some of the priests of the new definition consider the existence in C of a usable generic pointer type to be a failing of the language too.
