[pacman-dev] Can the update of a package induce the update of its depends?

Hi!
When I was thinking on the symlink puzzle, I ran into the question above.
Let me explain:
Suppose, that an updated version of audacious moves from /usr to /opt; 
and user does a "pacman -S audacious". In this case the installed 
audacious-plugins will be broken, because it thinks that audacious is 
installed to /usr. The dir change of audacious wasn't planned so 
audacious-plugins simply depends on audacious (with no version number), 
so audacious-plugins won't be updated. To avoid this, the package 
maintainer can do some ugly tricks only (conflicts, install_script/warn 
etc.). So it would be useful, if the maintainer somehow could record to 
the repo that there was a big change between audacious 2.0-1 and 2.0-2; 
so if user updates from a <=2.0-1 version to a >=2.0-2 version this 
will induce the update of audacious' depends (we can assume, that the 
updated version of audacious-plugins works fine with the updated 
audacious.). Or we can define a special ("major") version number, whose 
change indicates a "recursive" update. Bye, ngaba
