I still believe debconf us possible to use for this - in its current 
form but with aid of additional logic (which possibly fits your view).

That text talks about _conffiles_ specifically, and one way to avoid 
that specific rule is using... debconf!

Where debconf is one such interface provided by the package.

I believe the spirit of §10.7.4 is to ensure that any configuration of a 
package not done explicitly by the user is done through the package 

One reason for that is to ensure that there is one well-defined place to 
report any bugs: the package!
