A word like "default" tends to create tension.  Extending existing idea
like "sensible-utils" package for "sensible-*" command wrapper seems to
be good idea.

As I read this and looking at our archive, we have:

Package sensible-mda (Priority: extra)
    * Packaged by: Richard Nelson <cowboy@debian.org>
    * Sendmail source package
    * On and after lenny (stable) (mail): Mail Delivery Agent wrapper
      used by dspam and sendmail
      procmail | maildrop | deliver

Package sensible-utils (Priority: required)
    * Packaged by: Clint Adams <schizo@debian.org>
    * Sensible-utils  source package
    * On and after squeeze (testing) (utils): Utilities for sensible alternative selection
      these scripts used to be part of debianutils
      this provides sensible-{browser,editor,pager}

If a command is expected to be always on the system, integrate it into
sensible-utils seems good idea ... especially for mta and syslog if
Clint agrees.

(If a command is an optional one on the system, create package like

Distribution choice can be expressed by the order of "Depends:" line.  But
installer can always override it peacefully by changing only one package.
