The release managers can override of course, but I disagree.  I think it's
important that this be documented in-line when you perform the upgrade
itself; I'm working on updating libpam0g to do that.

I've mostly been delayed because libpam0g is the wrong place for this
question - it belongs to libpam-modules, but libpam-modules would need to
ask in the package preinst and is a transitively-essential package, so I'm
trying to make sure I get the semantics right here before uploading
anything.
