Nice feature but I think you need to keep an eye on versions of deps.  
I don't know that "port deactivate kde4 && port activate kde3" would  
revert kde3 deps that may have been upgraded to an unusable version.

Maybe keeping track of what was installed prior to upgrading could be  

port -q rdeps --no-build kdelibs3 | sed -e 's/^[[:space:]]*//' | sort  
| xargs port -q installed >> rdeps_kdelibs3.txt.
