It's nice indeed, and I've been tempted more than once to (ab)use execute 
checks like this.  Unfortunately this also clutters the logs with error 
messages, which IMHO shows it's a hack indeed.
I do miss conditional dependencies once in a while...e.g. a dependency that is 
fulfilled if at least/at most one of a list of packages is installed.  Or a 
dependency that is only triggered under some circumstances.  Something along 
the lines of boolean chec conditions for building the dependency tree.
