That is correct.

There's not an automatic way to do that, no. If you still have the non-universal versions installed, you can just reactivate them. Otherwise you will have to reinstall them.

It might be neat to have a script to automate this. It could notice if you have any universal ports installed that aren't required to be universal and offer to reinstall them non-universal.
