For the split second between the dpkg-divert and the ln call on install
or between the rm and dpkg-divert on removal. I think you are too
conservative there.

You are refering to "between the time that dpkg installs it and the time
that ldconfig is run in the postinst script", right? But the disapearing
would be only for a split second while your postinst runs.
