I've alreadly thought about that.  It is a good alternative to having to
make everyone recompile their programs.  If I have a future version that
exceeds the size of the upcoming one (Rigel 1.0) I will probably have to
do this.  I have, however, left myself a substantial buffer at the end
of Rigel (allowing for bug fixes and quite possibly future expansion). 
Most expansion (more ROM calls, etc.) will be supported through
libraries.  I suppose library support is almost essential if fixed
address relocation is used within an OS.
