We also do a lot more than change a table under the covers, so getting
access to this would not help.

If you detach the branch graph which contains the OrderedGroup, rearrange
the OrderedGroup, then reattach again, you will get better performance
that attaching and reattaching the children of the OrderedGroup individually.

It is true that only BranchGroup nodes may be added or detached from a
live or compiled scene graph. In your case simply make the parent of
your OrderedGroup be a BranchGroup and use it as the detach point. If
you have set all the appropriate capability bits, it doesn't matter if
anything is live or compiled.
