I think deb-orphan (or something like that) will help you find packages that do 
not fulfill dependencies for any other package.  Perhaps this could be part of 
a strategy to help identify which packages to remove?

I also would like a package's dependencies to be removed when I remove a 
package so long as those dependencies aren't needed by any other package.  I'd 
like a chance to override this, but in the vast majority of cases I don't want 
unused packages on the system because I would rather use the space they occupy 
for other things.
