Did you check out debian-policy? I looks like you are replying to an old
email here and the discussion did continue on debian-policy.
Note, that you are not "killing" an idea--it's quite the opposite: my
latest proposol was much more restrictive then yours.

AFAIK, base packages are not garantueed to be installed. Thus we should
probably not allow the use of such programs.
And didn't you say that "Pre-Depends" should not be used in connection
with a postinst script since this is too dangerous? (just wondering...)

Does this sentence conflict with the above?
