I'll point out that I'm not a kde expert by any means, but as long as
you keep track of what you are doing, I don't think this is an issue.
You should be able to go back to the starting set of ports without a
problem.  Of course if you upgrade some dependency and then rebuild a
dependent port based on the new version, you can't necessarily revert
the dependency and keep the new dependent, but you could just revert
BOTH of them back to the "old" versions and you'd be back to your
starting point.
