Well, this is not completely unrealistic, given that somebody might do
--get-selections on one machine, and use it for --set-selections on a
different one.

Therefore the next question is: Is there a particular, defined order for
package removals? I think usually first all packages are removed, then
purged (i.e. 
prerm1, dpkg_removes_files1, postrm1 remove, 
prerm2, dpkg_removes_files2, postrm2 remove, 
prerm3, dpkg_removes_files3, postrm3 remove, 
postrm1 purge
postrm2 purge
postrm3 purge

This would be okay for me. But if it happens to be 
prerm1, dpkg_removes_files1, postrm1 remove, 
postrm1 purge
prerm2, dpkg_removes_files2, postrm2 remove, 
postrm2 purge
prerm3, dpkg_removes_files3, postrm3 remove, 
postrm3 purge

for some reason, I am in trouble. Can I make any assumptions about this?
