It really depends on what you are using these commands for example if need to receive apple events then you should test to make sure it working. For example if you use an apple script to open or quit omnis you should test this script in omnis 8 to make sure it’s still working. I believe all of these commands have to do with apple scripting so it’s a good idea to find out why these were added and then test this functionality.
From what I can tell it there isn’t a lot of info on what to do if the command is deprecated just that is was deprecated.
