If you change the size of a regset, then the new full size will be the size of the core file notes. Existing userland tools will not be expecting this, they expect a known exact size. If you need to add new stuff, it really is easier all around to add a new regset flavor. When adding a new one, you can make it variable-sized from the start so as to be extensible in the future. We did this for NT_X86_XSTATE, for example.
