What are you trying to achive? Do you want some sort of tool to pre-scan
all the .debs, configure them then install?
A script is necessary in the pre/postinst no matter what you decide as
that is the only time configuration information can be transformed into
package config files.
A script MAY NOT be necessary to actually run the configuration. Bluntly,
if a script is needed for more than 15% of the cases then we have failed,
the system is too complex to work with.

Is this important? It doesn't hurt if the question is asked, all that
happens is that the user becomes confused and a bit of space is wasted.

Yep - but perhaps there are other ways than what you are describing..
