Such hooks for pkg_add and pkg_delete commands can also be used for
building a custom package database.  Many people want it (not me). Or
a database that links filenames to package name or something similar.
For this, it is only necessary to provide two types of hooks: 'register'
and 'unregister' and provide an easily parseable information about
package, i.e. list of files in it, size, checksums etc.

I even think that normal actions for 'register'ing and 'unregister'ing
actions (i.e. creating things in /var/db/pkg) can also be implemented
with a help of such hooks.
