MacPorts and ports can add users, but MacPorts doesn't remove them. I'm not sure how we could change that. Suppose you install a port that has a user that needs to own some data, such as postresql96-server. You then uninstall the port, which then hypothetically removes the user. Now the databases you created with that port are owned by a userid that doesn't exist anymore. Now you reinstall the port, which creates a postgres user but with a new userid. This creates more work for the user: needing to reassociate files the port needs with the new userid.
