The restrictions for using these globals only apply to the parameter script, and master script run as parameter script. One of the main reasons is to prevent stored parameter inconsistencies of a placed object in different view settings. The aforementioned globals will work in every other script. Sorry for repeating again, if you meant the same, but I wanted to make sure the parameter/master script only restriction is registered.
