As you say GS doors and windows are very complex with many macros, and macros calling macros.
The hideparameter all command will be in one of those macros somewhere I am sure.
If it is not in the parameter script it could possibly be in the master script (but I don't think so).
If I get a chance later I will load the GS library and have a look around (I don't actually use it).
