Surely, in a homenet, it's very much the case that (as Fred has hinted over in 6renum) the issue is "numbering" rather than renumbering. I may be too much of an energy conservation nut for most people, but my homenet is cold-started and numbered most mornings, because it is powered off at bedtime. However, I can see no harm in sticky subnet numbering, as long as the new prefix isn't long enough to overwrite the old subnet numbers. > You'll notice > in my draft that if the autoconfig prefix is withdrawn, I > expect prefixes dependent on it to be withdrawn, and if > stored in permanent storage, erased.
