I'm splitting this thread, to talk a bit more about library updates.

I'll drill the topic some more. What if a dependent package becomes
orphaned? Suppose there's CSWlibfoo, which has been updated, but
package CSWbar depends on it, the maintainer vanished inside a black
hole and nobody is willing to pick the package up. Are there any
deadlines? Does the importance of CSWbar matter?

Ideally, I'd like it to be there a page which describes how to deal
with library updates, along with the process of phasing out old
library versions. Can one of the elders write it? If not, I'm going to
do it myself, and Trygve is going to start telling me why what I wrote
is wrong... ;-)
