I don't object to this change.

| $OCTAVE_PREFIX/share/octave/$version/m/startup/octaverc

| Environment variable: OCTAVE_LOCAL_SITE_INITFILE which defaults to

Did you mean rename the first since it's the one that contains the
version info?

OK, now I'm confused about what the final arrangement of variables and
values will be.  Maybe it would be clearer if you just sent a patch
showing what you want to do.
