Debuggers need to know about the stack frame and so it already has became
a part of the ABI, if we want or not. You may recall the great pain I
went through to maintain compatibility in the past when changes were
necessary for example to support the DSP ASE. But to some degree the
stackframe is a function of hardware development which I don't control
so I can only give a best effort type of guarantee ...
