Ah, sure.

Admin installs adduser. adduser defaults to /home.
Admin now installs your package. adduser now defaults to /srv/home.
Admin changes adduser's default to /u but keeps all other changes
  your configuration package makes, as they only disagrees with this one.
Admin runs apt-get upgrade, pulling in a new micro version of your
  package that changes something totally unrelated to adduser.
Now, adduser MUST NOT change away from /u.

At least in Debian packages… but yes, configuration management is
hard, and will remain so at least as long as #48717 (yes, five digits)
is not fixed.
