This functionality is useful for stubs that need to walk the stack. The new machine operator, LoadParentFramePointer dosn't force the currently compiling method to have a frame in contrast to LoadFramePointer. Instead, it adapts accordingly when frame elision is possible, making efficient stack walks possible without incurring a performance penalty for small stubs that can benefit from frame elision.
