Case: package removed from CRAN, but not orphaned

Just a tiny update: 

  Thanks to the great new "packdep" package, it's very easy
to find out how many of the packages on CRAN have *no* reverse
dependencies:

library(packdep)
d1 <- map.depends()
c <- dependencies(d1)
sum(c$reverse==0)/nrow(c)

  66%.  Furthermore, I would guess that orphaned packages would be
more likely to be in this 66%.  What about exempting packages with
any reverse dependencies from the auto-orphanization process?
